Gram equivalent weight is expressed in grams per mole (g/mol), similar to gram molecular weight. However, gram equivalent weight is often represented as grams per equivalent (g/eq) to emphasize its role in reactions involving equivalents of hydrogen ions or electrons.
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.
8 mar 2020 · A gram equivalent (geq) is the number of grams of substance present divided by its equivalent weight. It can also be expressed as the number of charge elements contained times the number of moles n.
In chemistry, equivalent weight (also known as gram equivalent[1] or equivalent mass) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.
