Dry air near sea level has the following composition byvolume: N2, 78.08 percent;O2, 20.94 percent; Ar, 0.93 percent;CO2, 0.05 percent. The atmospheric pressureis 1.00 atm. (Hint: Since volume is proportional to the number ofmoles present, mole fractions of gases can be expressed as ratiosof volumes at the same temperature and pressure.)
