A certain amount of chlorine gas was placed inside a cylinder with a movable piston at one end. The initial volume was 3.00 and the initial pressure of chlorine was 1.50 . The piston was pushed down to change the volume to 1.00 . Calculate the final pressure of the gas if the temperature and number of moles of chlorine remain constant.. (Figure 1)
