Description:
Number of molecules in one gram-molecular weight of a compound is 6 0221 367 x 10 ‘23. For example, the molecular weight of oxygen is 32.00, so that one gram-mole of oxygen has a mass of 32.00 grams and contains 6.0221367 10{sup 23} molecules. The volume occupied by one gram-mole of gas is about 22.4 l (0.791 cubic feet) at standard temperature and pressure (0 C, 1 atmosphere) and is the same for all gases, according to Avogadro's law.
