Acertain amount of chlorine gas was placed inside a cylinder with a movable piston at one end. the initial volume was 3.00 l and the initial pressure of chlorine was 1.60 atm . the piston was pushed down to change the volume to 1.00 l. calculate the final pressure of the gas if the temperature and number of moles of chlorine remain constant
