An unknown gas occupies a volume of 0.075 m3, has a pressure of 0.500 MPa, and a temperature of 47°C. You determine that the gas is either CO2, O2, N2, or CH4. Using the volume, pressure, and temperature given, determine the mass that would be expected for these four gases. If you measure the mass to be 0.441 kg, which of the four gases is the unknown gas likely to be?
