    • The equivalent weight of an element is calculated by dividing its atomic weight by its valence.
    • In acid-base reactions, the equivalent weight of an acid is its molar mass divided by the number of replaceable hydrogen atoms.
    • Chemists use equivalent weight to determine the proportions of reactants in a chemical reaction.
