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.
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.
Equivalent weight is the mass of a substance that reacts with or replaces one mole of hydrogen ions or electrons. It is expressed in grams per equivalent. On the other hand, gram equivalent is the mass of a substance that reacts with or replaces one gram equivalent of hydrogen ions or electrons.
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.
18 cze 2024 · Both gram equivalent and equivalent weight represent the mass of a substance that can participate in a single reaction with a fixed amount of another substance. Although they are very closely related to concepts, there is a difference between gram equivalent and equivalent weight.
24 wrz 2024 · The mass of an acid or a base that will release or neutralize one gram molecule (mole) of hydrogen ion. A 1-mole solution of H 2 SO 4 contains 2 gram equivalents. A thousandth of a gram equivalent weight is a millequivalent. See normal solution.
