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. Since volume is proportional to the number of moles present mole fractions of gases can be articulated as ratios of volumes at the same temperature and pressure.
(a) Compute the partial pressure of each gas in atm.
(b) Evaluate the concentration of each gas in moles per liter at 0°C.
