A vessel of volume V = 30 litre is separated into three equal parts by stationary semi permeable membrane . The left , middle and right parts are filled with `m_(H) = 30` gm of hydrogen , `m_(O_(2)) = 160` gm of oxygen and `m_(N) = 70` gm of nitrogen respectively . The left partition lets through only hydrogen while the right partition lets through hydrogen and nitrogen . If the temperature in all is 300K , the ratio of pressure in the three compartments will be :
