The initial temperature and pressure of the oxygen are, Oxygen is cooled untu" the specific volume becomes 0.15 m/kg while it behaves as an ideal gas, and if the total work done on the System is 300 kJ, Calculate the mass of the oxygen in kg using 5 signifigant fAgures. respectvely , 200°C and 0.le MPa.
