Awelder using a tank of volume 7.20 x 10^−2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.20 x 10^5 pa and temperature of 39.0°c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 20.9 °c, the gauge pressure of the oxygen in the tank is 1.85 x 10^5 pa.
part a) find the initial mass of oxygen.
part b) find the mass of oxygen that has leaked out.
