A container has a volume of #18 L# and holds #7 mol# of gas. If the container is compressed such that its new volume is #8 L#, how many moles of gas must be released to maintain a constant temperature and pressure?
Let n moles of gas to be released .
As the temerature and pressure of two gases are same their volume should be proportional to their respective no. Of moles as we know from Avogadro's law.
