A welder using a tank of volume7.50×10−2 m3m3 fills it with oxygen (with amolar mass of 32.0 g/molg/mol ) at a gauge pressure of2.85×105 PaPa and temperature of35.2 ∘C∘C. The tank has a small leak, and in time some of theoxygen leaks out. On a day when the temperature is 21.7 ∘C∘C,the gauge pressure of the oxygen in the tank is1.60×105 PaPa .
