An “empty” aluminium scuba tank contains 11.0 L of air at 21°C and 1 atm. When the tank is filled rapidly from a compressor; the air temperature is 42°C and the gauge pressure is 2.10 x 107 Pa. Air is about 78% nitrogen, 21% oxygen, and 1% miscellaneous; its average molar mass is 28.8 g/mol = 28.8 x 10-3 kg/mol. Estimate the mass of air that was added.

Question
An “empty” aluminium scuba tank contains 11.0 L of air at 21°C and 1 atm. When the
tank is filled rapidly from a compressor; the air temperature is 42°C and the gauge
pressure is 2.10 x 107 Pa. Air is about 78% nitrogen, 21% oxygen, and 1%
miscellaneous; its average molar mass is 28.8 g/mol = 28.8 x 10-3
kg/mol. Estimate the
mass of air that was added.
