A container has a volume of #2 L# and holds #1 mol# of gas. If the container is expanded such that its new volume is #8 L#, how many moles of gas must be injected into the container to maintain a constant temperature and pressure?
4 moles of gas must be injected into the container.
Let's use Avogadro's law:
The number 1 represents the initial conditions and the number 2 represents the final conditions.
• Identify your known and unknown variables:
• Rearrange the equation to solve for the final number of moles:
• Plug in your given values to obtain the final number of moles:
