Dry air near sea level has the subsequent composition by volume N2, 78.08 percent O2, 20.94 percent Ar, 0.93 percent CO2, 0.05 percent. The atmospheric pressure is 1.00 atm. Ever since volume is proportional to the number of moles present mole fractions of gases can be expressed as ratios of volumes at the same temperature and pressure.
Compute the concentration of each gas in moles per liter at 0°C.
