Oxygen (molar mass 32 kg/kmol ) expands reversibly in a cylinder behind a piston at a constant pressure of 3 bar. The volume initially is 0.01 m3 and finally is 0.03 m3; the initial temperature is 18.97 0C. Calculate the mass of oxygen with the correct unit to four decimal places. Assume oxygen to be a perfect gas and take the specific heat at constant pressure as =  0 . 9 1 7 k J / k g K and molar gas constant as  =  8,314  J / kmol K
