Formula Weight Versus Molecular Weight

Copper and aluminum can be combined to form a copper-aluminum alloy. An alloy is a mixture, and therefore does not have a chemical formula. However, under very high temperature, copper and aluminum can form a solid solution.

The molecular weight of a substance, also called the molar mass, M, is the mass of 1 mole of that substance, given in M gram. In the SI system the unit of M is [kg/kmol] and in the English system the unit is [lb/lbmol], while in the cgs system the unit of M is [g/mol].
