How to calculate equivalent weight of an acid when equivalent mass of

1.	How to calculate equivalent weight of an acid when equivalent mass of metal is given.
Answer» .Equivalent weights may be calculated from molar masses if the chemistry of the substance is well known: sulfuric acid has a molar MASS of 98.078(5) g mol−1, and supplies TWO moles of hydrogen ions PER mole of sulfuric acid, so its equivalent weight is 98.078(5) g mol−1/2 EQ mol−1 = 49.039(3) g eq−1.
