A container has a volume of #4 L# and holds #2 mol# of gas. If the container is expanded such that its new volume is #14 L#, how many moles of gas must be injected into the container to maintain a constant temperature and pressure?
7 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.
