a If we take air to be a mixture of about four molecules of nitrogen to one of oxygen, the mass of 1 mole of air will be about 28.8 grams. One mole of any substance contains about 6 × 1023 molecules. So there are about 1.04 × 1044 molecules in the Earth's atmosphere.
b At 101.325 kPa (abs) and 15 °C, air has a density of approximately 1.225 kg/m3 (or 0.00237 slug/ft3), about 1/1000 that of water according to ISA (International Standard Atmosphere).
