A container has a volume of #5 L# and holds #2 mol# of gas. If the container is expanded such that its new volume is #12 L#, how many moles of gas must be injected into the container to maintain a constant temperature and pressure?
The number of moles is
We apply Avogadro's Law (Temperature and Pressure constant)
The initial volume is
The initial number of moles is
The final volume is
The final number of moles is
The number of moles to be injected is
