Watch this video to understand the concepts of mass and weight! experimental molar mass for butane. ù Mass refers to the amount of matter in an object, and it is not dependent on gravity; your mass on Earth would be the same on the moon. (insert photo of student notebook) I remind the students that we learned how to use the spring scale and balance at the beginning of the year and that we would be using them in the investigation today. In this lab you will improve your project by creating a top-down program with separate functions as follows: A function that prompts the user for their weight, checks to make sure the weight entered is between 90 and 250 pounds, allowing the user to try again repeatedly if not, and returns that weight: int getEarthWeight(); • A function that prompts the user to select a planet, checks to make sure the selection is between 0 and 3, allowing the user to try again repeatedly if not, and returns that choice: int selectPlanet(); • A function that calculates the new weight depending on the planet selected and weight on earth, having the selection as a parameter and returning the new weight: int getNewWeight(int planetSelection, int earthWeight); The main function should control the flow of the program, providing an opportunity to continue entering new planets, just like in Lab 1a. Products/Reactants For this lab, the reactant is an unknown liquid. 2334) mass 2.35 Kg: a=0.5* 1/2.35 = 0.215 (Answer: 0. Mass: the amount of matter in an object. The purpose of this lab is to determine if the rotational equilibrium condition, Στ = 0, holds experimentally. Do this by first moving the small weight to the right. If you were on a different planet, your weight would be different. Step 3 Dissolve the acid in approximately 50 mL of deionized water. Click Next and verify that the Live Values are different. The answers to the following questions need to be a part of your discussion section. Pre-lab questions Possible answer: Butane is extremely flammable and will ignite. If atoms were as large as beans they could be sorted, counted, and massed. Ahmed Musawar . Mass is the amount of matter in an object. (I do a quick review with the students on how to use these tools). For example, your body's mass is a set value, but your weight is different on the Moon compared with on Earth. Possible answers: 0° … Lab 1a v.2 Weight is dependent on the mass of the object and the pull of gravity on Earth, using the simple formula W = mg. Printer Friendly Version: Purpose The purpose of this lab is to acquaint the student with the properties of oscillatory motion using an inertial balance, the use of the LabPro motion detector, and data analysis techniques that will show the relationship between the variables for period and mass. 2. • Venus: 8.83 m/s2 • Earth: 9.81 m/s2 • Mars: 3.75 m/s2 The program should define appropriate constants and variables, prompt the user and scan in their response, do the proper math, and output the results in a complete sentence. Use the triple beam balance that it is at your table as a guide. This includes hands-on activities as well as PhET use ideas. int mercuryWeight(int wt){ Question: Are Mass And Weight Directly Related? simple pendulum consists of string that is attached to weight at one. Compare the masses and weights of objects on Earth, Mars, Jupiter, and the Moon. Pre-lab questions Possible answer: Butane is extremely flammable and will ignite. One of you is an expert in calculating someone's age on different planets and the other is an expert in calculating someone's weight. PURPOSE In this experiment, you will perform the necessary calculations to determine the atomic mass of the fictitious element vegium. Weight Is The Force Exerted On Object Due To Gravity. Evidence (give evidence from the lab) Answers may vary Reasoning (show your scientific reasoning) The Law of Acceleration says that the smaller the mass, the greater the acceleration. In a 250-mL beaker, weigh out 0.3 to 0.4 g of your unidentified acid and record the mass exactly. In the U.S. customary system, there is no unit for mass and the unit for weight is pounds. PAGE \* MERGEFORMAT 3 ! Sign in Register; Hide. The carbon dioxide gas is produced by the reaction of calcium carbonate with hydrochloric acid. é Course. Student Exploration: Weight and Mass - Lesson Planet. Balance. } 3) Which instrument do you use to measure mass, and what is the unit of measurement? First, mass percent is calculated as the mass of the solute divided by the total mass of the solution. Vocabulary: balance, force, gravity, mass, newton, spring scale, weight. (By Archimedes’ principle, volume of body = volume of the liquid displaced by the body.) State how they are related to each other. As a result of changing the instrument, we measured either the weight or the mass. Explore/Explain. With a decrease in the mass of vapor and a constant number of moles, the molar mass will be reported too low. 3. Scale return wt*8.83/9.81; Weight and Mass. Principles Of Physics (PH 101) Uploaded by. Molecular. A high-speed object (say, moving at 200 mi/hr) will weigh less than the same object when at rest.

In order to sense weight, you have to be near a second planet sized object that has a lot of mass. We were given several different quantities "Candium" atoms which represented different isotopes, and a scale. You will submerge the object into the catch can. í ... Then, a discussion of weight versus mass follows. PH-101 lab #9 - Lab report. From weight and mass worksheets to measuring mass and weight videos, quickly find teacher-reviewed educational resources. Mass is a measure of the amount of matter contained by an object, while weight is a measure of the gravitational pull on an object. 2. As a result of changing the instrument, we measured either the weight or the mass. Using more physics and mathematics terms, weight is defined as the force with which a body is attracted to Earth or another celestial body, equal to the product of the object's mass and the acceleration of gravity: gravity = mass x acceleration due to gravity, which is constant (Earth = 9.8 m/sec2). It is measured in kilograms (kg) or grams (g). Queensborough Community College. for this lab we are trying to verify that gravity on earth is 9.81 using simple pendulum. Weight Lab Activities. Lima beans vary greatly in size, thus having the largest uncertainty. Share. The calculated number of beans in one relative mass stayed the same at 16.7 ± 0.1 bean. Although the difference between mass and weight is real, on Earth mass and weight are very similar. Weight, or the gravitational attraction between two objects with mass, is influenced by two factors: the amount of matter an object has (mass) and the distance between them. Mass is the property that an object has that makes it hard speed it up or slow it down. Then zip up the entire project and submit it to the Lab la assignment for grading. laboratory by an instrument called a mass spectrometer. Hypothesis If you weigh an item on a spring scale and it weighs three Newtons, then the items mass will be _______ grams, because one Newton is equal to approximately 100 grams. Coz Mass of steel ball =27g Volume of steel ball = 50cm^3- 20cm^3 =30cm^3 Density of steel ball = mass /volume rho = 27g/30cm^3=0.9gcm^-3. We … This Student Exploration: Weight and Mass Graphic Organizer is suitable for 7th - 8th Grade. | WS 3.3 Atomic Weight and Ions For Students 10th - 12th. Weight and mass are two commonly misunderstood terms in fluid mechanics and mechanics. I need a code for lab 1c (3rd one). Remember, the smallest weight marks single grams, and the lines between the numbers on that beam mark tenths of grams. Equivalent weight and molar mass have units shown below: Equivalent weights may be calculated from molar masses if the chemistry of the substance is well known. Question: MASS VS WEIGHT In This Lab We Will Explore The Relationship Between Mass And Weight. depending on what planet they choose. Then convert their weight into Mercury pounds or Venus pounds, etc. The mass of one mole of HCl would therefore be its equivalent weight. Since the mass of one mole of HCl is also its molar mass (MM), its equivalent weight and molar mass have the same numerical value. Suppose you step on a bathroom scale on the Moon. simple pendulum consists of string that is attached to weight at one. does anyone know :P Data With a decrease in the mass of vapor and a constant number of moles, the molar mass will be reported too low. “Zero balance” your balance and scale To zero your spring scale, adjust the level until it lines up to zero. 4. These activities demonstrate the difference between mass and weight. Terms Lab investigating the properties of density, volume, mass, and weight and their differences. 2. Lesson Planet. // venus weight For the balance, once the weights have been positioned so that the beam pointer aligns with the mark on the post, add each of the marked weights together to get a total. Controls: 1. If you cannot zero the balance, ask a teacher for help. Keep your fingers and toes out of the way of the moving objects. Discover that the weight of an object changes when it is moved to another planet. Explain by using the data you obtained in your answer. experimental molar mass for butane. When we used the balance we measured the mass; when we used the spring scale we measured the weight. 1. Distinguish between mass and inertia. In this experiment the molecular weight of carbon dioxide will be determined. #include <stdio.h> Weight Is The Force Exerted On Object Due To Gravity. By doing this, we will be able to tell what the molar mass of the liquid is. Your lab report will have, labeled with roman numerals: I Introduction Section, II Materials Section, III Data Table Section, IV Calculations Section, V Conclusion section VI Questions . Be sure to include the units. 30 minutes. One of the main goals of this lab is to allow students the opportunity to differentiate between atomic number (protons) and atomic mass (protons+neutron). Dean used a triple beam balance to find out that the mass of a rock was 40 g. Dean then used a graduated cylinder to find out the volume is 5 ml. Measuring Mass Lab: 50 points possible.
