question

Calculate the number of moles of air in a column 1 cm^2 in area and rising from sea level to an altitude of 1.5 × 10^6 cm (about 10 miles), allowing for the barometric decrease in pressure. Assume air to be a uniform gas of molecular weight 29, and a uniform temperature of 0°C. Note that the atmospheric pressure is equal to the total weight of gas in a column of unit area and of infinite height. Conversion factors: R = 0.082 liter-atm/mole-deg = 8.31 × 10^7 ergs/mole-deg = 1.98 cal/mole-deg; 1 atm = 760 mm Hg = 1 × 10^6 dynes/cm^2.
