A container has a volume of #15 L# and holds #9 mol# of gas. If the container is compressed such that its new volume is #8 L#, how many moles of gas must be released from the container to maintain a constant temperature and pressure?
According to Ideal Gas equation
Now moving on to the second condition
Dividing (I) and (II)
Since the given conditions are same for both the cases, These can be canceled out..... So we are left with
Therefore 9 - 4.8 moles need to be removed
