    The formula mass of a molecule is the sum of the atomic weights of the atoms in the empirical formula of the compound. It is also known as Formula Weight.

    The atomic weights of

    N = 14.01 amu

    H = 1.00 amu

    P = 30.97 amu

    O = 16.0 amu

    Now, we will calculate now the formula mass of a given substance

    3 (14.01) + 12 (1.00) + 1 (30.97) + 4 (16.0) = 42.03 + 12.00 + 30.97 + 64.0 = 149.0 amu

    Therefore, the formula mass for (NH4) 3PO4 is 149.0 amu
