The assignments that must be completed are:
Complete the pre laboratory writing assignment before the lab sessions begins.
Attempt the pre laboratory problems as a document before the lab session.
Using the class data provided in the experiment to complete ALL trials of Part A. Determine the value of the ideal gas constant, R, for each trial given in the class data.

Using the videos to view Part B of the laboratory assignment to complete the data table and create the appropriate graphs to show Boyle's Law relationship of Pressure and Volume.
Use the provided data in the class data of temperature and pressure to show the relationship of GuyLussac's Law. Determine the value of Temperature when pressure is zero. The simulation can be used to see how the pressure changes as a function of temperature.
Complete the formal laboratory report for this assignment.
Discussion
Discussion
The ideal gas law and the individual gas laws (Boyle's, Charles' and Amonton's laws) define how the measurements of pressure, volume, temperature and number of particles (moles) are related. We will determine the Ideal gas constant by measuring the pressure, volume and temperature of a collected gas. By calculating the moles of gas, R can be determined.
Pre laboratory writing
Pre laboratory writing
Complete the pre laboratory writing assignment in your laboratory notebook. The prewriting must be completed before the laboratory session begins. The writing should include a purpose/hypothesis of the experiment, a discussion or theory, a detailed step by step summary of the procedure explaining what data will be collected and how you will collect it. Data Tables or space to collect the data should be included within the procedure discussion. Look up any SDS on chemicals you are not familiar with.
Use this simulation to answer the last questions in the pre laboratory problems document:

The demonstration and computer simulation will help students explore all three levels of representation of Amonton's Law, i.e. following Johnstone's Triangle, and it will help make the connection to the Kinetic Molecular Theory. The qualitative demonstration takes about five minutes to perform.

You can find the number for R in any textbook, but where did it come from in the first place? In this video, we show how to derive the universal gas constant used in the ideal gas law.

DrJoeBentley show a method of experimentally determine the ideal gas constant. Although this experiment uses magnesium metal instead of zinc metal the set up is very similar.
I have walked through the calculation of R from the experimental measurements taken in the first video above. Use this video to see how the ideal gas constant was determined from the data collected:

The Sci Guys: Science at Home - SE2 - EP11: Gay-Lussac's Law of Ideal Gases
The Sci Guys - Welcome to the eleventh episode of season 2 of The Sci Guys. In this episode we will be using candles, water and a beaker to explore one of the gas laws, named Gay-Lussac's law of ideal gases. We will show you how the temperature and pressure of an ideal gas are directly proportional and explain why gases follow Gay-Lussac's gas law. Gay-Lussac's law specifically works on ideal gases. Examples of gases that act like ideal gases are oxygen, hydrogen and carbon dioxide. At the end of this video you will be able to demonstrate with an experiment how Gay-Lussac's law of gases works and explain how gas molecules react to changes in temperature and pressure.
