Reference no: EM13236215

A welder using a tank of volume 7.90×10?2m3 fills it with oxygen (with a molar mass of 32.0g/mol ) at a gauge pressure of 3.00×105Pa and temperature of 38.8?C. The tank has a small leak, and in time some of the oxygen leaks out. On a day when the temperature is 22.7?C, the gauge pressure of the oxygen in the tank is 1.60×105Pa .
