A container has a volume of #18 L# and holds #9 mol# of gas. If the container is compressed such that its new volume is #12 L#, how many moles of gas must be released from the container to maintain a constant temperature and pressure?
The answer can be determined by using Avogadro's law:
The number 1 represents the initial conditions and the number 2 represents the final conditions.
Let's identify our known and unknown variables.
Rearrange the equation to solve for the final number of moles:
Plug in your given values to obtain the final number of moles:
