A welder using a tank of volume 7.50×10−2 m3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.25×105 Pa and temperature of 37.9 ∘C. The tank has a small leak, and in time some of the oxygen leaks out. On a day when the temperature is 22.6 ∘C, the gauge pressure of the oxygen in the tank is 1.60×105 Pa .

Part A

Find the initial mass of oxygen. (in Kg)

(Following the steps submitted by another person for this problem, I got the mass = .301616 Kg and it was wrong)

Part B

Find the mass of oxygen that has leaked out. (in Kg)

If you are able, please include your steps so I can understand the math. Thank you for your help.
