A container has a volume of #72 L# and holds #6 mol# of gas. If the container is compressed such that its new volume is #36 L#, how many moles of gas must be released to maintain a constant temperature and pressure?

Answer:

#3 "mol"#

Explanation:

We imagine the molecules of the #6 "mol"# of gas to be evenly distributed within the #72 "L"# container.

Now, we put a partition at the center of the container to divide the container into 2 - #36 "L"# containers.

Each #36 "L"# container will take half the original amount of gas. (There is no reason why one side should have more than the other) So that would be #6 "mol" xx 1/2 = 3 "mol"#.
