It is OK to use your textbook or lecture notes from class, but if you can answers the questions without it that is OK too.

Do not press the RETURN or ENTER key while you are answering these questions. Your browser will interpret either the same as clicking on the Submit key.

Answer all of the questions below. If you do not know an answer enter CNA. However, it will help me the most if you answer each question with your best intuition/idea about what would be a reasonable answer.

First Name:

Last Name:

Laboratory Section:

1. What are the units on each of the variables in the ideal gas equation?

PV = nRT






2. If a gas sample has a temperature of 32.5 degrees Celsius, what is the temperature of the gas in Kelvins? Kelvins

3. What is the volume of 1 mol of an ideal gas at 273 K and 1 atm of pressure?


4. A fixed amount of an ideal gas at 25 °C exerts a pressure of 748 torr in a 10.0 L container. If the pressure is increased to 1500 torr what is the volume (in liters) of the gas assuming the temperature and the amount of gas are held constant?


5. What is the temperaure (in Kelvins) of a sample of an ideal gas if 1.5 moles of the gas occupy a volume of 27 liters at 1.1 atm.


6. Calculate the molar mass of a gas if 2.50 g occupies 0.875 L at 0.900 atm and 35 °C.

g mol-1

7. Is there anything about the questions that you feel you do not understand? List your concerns/questions.

8. If there is one question you would like to have answered in lecture, what would that question be?
