A container has a volume of #18 L# and holds #24 mol# of gas. If the container is expanded such that its new volume is #54 L#, how many moles of gas must be injected into the container to maintain a constant temperature and pressure?
72 moles of gas must be injected into the container.
The answer can be calculated by using Avogadro's law:
The number 1 represents the initial conditions and the number 2 represents the final conditions.
