    You use the atomic mass. Multiply each element by its atomic mass on the periodic table. Then add the totals up.

    Here are the masses of all the elements in the second chemical compound. potassium | 39.0983 u (unified atomic mass units) phosphorus | 30.973762 u (unified atomic mass units) oxygen | 15.9994 u (unified atomic mass units)

    From the compound we get, K*3 + P + O*4 = K3PO4 = 39.0983*3 + 30.973762 + 15.9994*4 =212.266262 u. U can be substituted for grams per mole or g/mol.
