1. Avogadro's hypothesis Equal volumes of different gases at equal temperatures contain the same number of molecules. Similarly, equal numbers of molecules in identical volumes and at the same temperature will exert the same pressure. (One mole of any gas will contain 6.02 × 1023 molecules and will occupy a volume of 22.4 L at a temperature of 0°C and a pressure of 760 mm Hg.)

++

2. Dalton's law In a gas mixture the pressure exerted by each individual gas in a space is independent of the pressures of other gases in the mixture, for example,

5. Ideal gas law

6. Henry's law The weight of a gas absorbed by a liquid with which it does not combine chemically is directly proportional to the pressure of the gas to which the liquid is exposed (and its solubility in the liquid).

++

7. Graham's law The rate of diffusion of a gas (in the gas phase) is inversely proportional to the square root of its molecular weight.
