Table A.1-2. Volume and Density

1 g mol ideal gas at 0°C, 760 mmHg = 22.4140 liters = 22 414 cm3

1 lb mol ideal gas at 0°C, 760 mmHg = 359.05 ft3

1 kg mol ideal gas at 0°C, 760 mmHg = 22.414 m3

Density of dry air at 0°C, 760 mmHg = 1.2929 g/liter = 0.080711 lbm/ft3

Molecular weight of air = 28.97 lbm/lb mol = 28.97 g/g mol
