Gram Molecular Volume or Molal Volume. One mole, or 32 grams of oxygen, under standard conditions occupies a volume of 22.4 liters. According to Avogadro s principle, the same volume would contain exactly 1 mole of any other gas under standard conditions this volume, therefore, assumes a great importance, and it is called the gram molecular volume or for brevity molal volume. 

Physical Properties.—Methane is a colorless and odorless gas. It is lighter than air and when pure may be readily liquefied. The weight of one liter of methane is o.7i46g. and 22.4 litres (gram molecular volume) weigh 16.00 g. It is, therefore, 7.952 times as heavy as hydrogen which, as may be recalled, weighs 0.08987 g. per liter. The density of methane is then 7.952, and its molecular mass is 16.00. 

To calculate the number of moles of A in the volume of gas A we have to decide what gram-molecular volume to use. For 0°C and 1 atm, the ideal gram-molecular volume is usually taken to be 22.4145 dm. The deviation factor may be expressed as follows ... 

In both these equations, p is the pressure, V is the gram molecular volume, R is the universal gas constant and Ti s the absolute temperature. In the second equation, b is a constant which is related to the...
