a welder using a tank of volume 7x10^-2 m^3 fills it with oxygen (with a molar mass of 32.0g /mol) at a gauge pressire of 3.25x10^5 Pa and temperature of 35.0°C. the tank as a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.3 °C the gauge pressure of the oxygen in the tank is 1.85x10^5 Pa. fi d the initial mass of oxygen. find the mass of the oxygen that has leaked out
