A container has a volume of #7 L# and holds #2 mol# of gas. If the container is expanded such that its new volume is #15 L#, how many moles of gas must be injected into the container to maintain a constant temperature and pressure?
Increase the amount of gas to 4.29 mol by injecting another 2.29 mol.
We can use the ideal gas law for this, written in its proportionality form:
If temperature and pressure are to be held constant,
