Consider the following setup, which shows identical containers connected by a tube with a valve that is presently closed. The container on the left has 1.0 mol of H2 gas; the container on the right has 1.0 mol of O2.

Acceptable answers to some of these questions might be €œboth€ or €œneither one.€
a. Which container has the greatest density of gas?
b. Which container has molecules that are moving at a faster average molecular speed?
c. Which container has more molecules?
d. If the valve is opened, will the pressure in each of the containers change? If it does, how will it change (increase, decrease, or no change)?
e. 2.0 mol of Ar is added to the system with the valve open. What fraction of the total pressure will be due to the H2?
