What Difference between molecular weight and equivalent weight

Question

Accepted Answer

Molecular weight is the sum of the atomic weights of all atoms in a molecule, while equivalent weight is the weight of a substance that reacts with or replaces one mole of hydrogen ions.

Molecular weight is expressed in atomic mass units (amu) or grams per mole (g/mol).
Equivalent weight is expressed in grams per equivalent (g/eq) or milliequivalents per gram (meq/g).
Molecular weight is used to calculate the amount of a substance in a given volume or mass.
Equivalent weight is used to determine the amount of a substance required to react with or replace a certain amount of another substance.
For example, the molecular weight of water is 18.015 g/mol, while the equivalent weight of sulfuric acid is 49 g/eq.
Molecular weight is important in determining the physical and chemical properties of a substance, while equivalent weight is important in stoichiometry and chemical reactions.
