A container has a volume of #19 L# and holds #8 mol# of gas. If the container is compressed such that its new volume is #5 L#, how many moles of gas must be released from the container to maintain a constant temperature and pressure?
By The equation of state for real gas we know
P = Pressure, V = Volume, n = number of moles of gas , T = Absolute temperature of the gas and R = universal gas constant.
In our case P and T are constant in both the case
So No of moles of gas to be released
