A container has a volume of #18 L# and holds #15 mol# of gas. If the container is expanded such that its new volume is #24 L#, how many moles of gas must be injected into the container to maintain a constant temperature and pressure?
The number of moles to be injected is
We apply Avogadro's Law
Initial volume is
