Question

Calculate the gram equivalent mass of h2so4​

Answer 1

Answer:

Equivalent weights may be calculatedfrom 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
