    Answer:

    Molar mass of H3PO4  = 97.99 g/mol (Approx.)

    Explanation:

    Find:

    Molar mass of H3PO4

    Given;

    Molar mass of H = 1.0079 g/mol

    Molar mass of P = 30.974 g/mol

    Molar mass of O = 15.999 g/mol

    Computation:

    Molar mass of H3PO4  = (1.0079)(3) + 30.974 + 15.999(4)

    Molar mass of H3PO4  = 3.0237 + 30.974 + 63.996

    Molar mass of H3PO4  = 97.9937

    Molar mass of H3PO4  = 97.99 g/mol (Approx.)
