Gram Equivalent Weight is used to measure the amount of a substance that can react with or replace a certain number of hydrogen ions or electrons. It is calculated by dividing the molar mass of the substance by its valence. On the other hand, Gram Molecular Weight is used to measure the mass of one mole of a substance.
The equivalent weight of an element is its gram atomic weight divided by its valence (combining power). Some equivalent weights are: silver (Ag), 107.868 grams (g); magnesium (Mg), 24.312/2 g; aluminum (Al), 26.9815/3 g; and sulfur (S, in forming a sulfide), 32.064/2 g.
