A welder using a tank of volume 7.50x10-2 m³ fills it with oxygen (with a molar mass of 32.0 g/mol) at a gauge pressure of 2.90×105 Pa and temperature of 37.5 °C. The tank has a small leak, and in time some of the oxygen leaks out. On a day when the temperature is 21.6 °C, the gauge pressure of the oxygen in the tank is 1.95x105 Pa . Part A Find the initial mass of oxygen. Express your answer in kilograms. m = kg Part B Find the mass of oxygen that has leaked out. Express your answer in kilograms.
