Lab: Determination of Ideal Gas Law Constant



The ideal gas law makes use of “R” - the universal gas constant. How do we know what the value of 'R' is? In this experiment, you will produce a gas and make some simple volume and temperature measurements that will allow you to calculate an experimental value for the ideal gas constant. You will then compare this experimental value to the accepted value.

View the Determination of ideal Gas Law Constant powerpoint and view the link below to help you with the procedure. This will provide you with the necessary foundation for safely and successfully completing the lab.

Notes:

  • The gas law lab directions tell the student to cover the top of the graduated cylinder with a finger to invert it into the water. A student sent me the following information to assist those with smaller fingers! "I just wanted to say that my fingers are too small to cover the top of the graduated cylinder, and I'm sure many other peoples fingers are too. But I found that if i used a rubber glove and pulled it tight around the top I could flip it over with minimal air really easily."
  • In the power point, note the correction to the error found in the units of % by mass in the investigation manual and includes the density for the hydrogen peroxide solution (1.00 g/mL) which is needed to complete the conversion of % by mass to molarity. Please use three significant figures for the percent by mass and the density and thus determine the molarity to three significant figures.
  • Remember that the volumes on the 50-mL graduated cylinder are read to +/- 0.1 mL( one place after the decimal point.).

Note:While you work on the lab,you are required to take certain images/photos of your labto document that you actually completed the lab yourself. Each photo should include anote card or a piece of paper with your name, the date you completed the experiment and your course section numberclearly visible.
