Webmolecular or molar mass ( amu or g mol) empirical formula mass ( amu or g mol) = n formula units/molecule The molecular formula is then obtained by multiplying each subscript in the empirical formula by n, as shown by the generic empirical formula A x B y: ( A x B y) n = A nx B ny WebAug 6, 2024 · The answers are 5C, 1N, and 5H. The empirical formula is C 5 H 5 N, which has a molar mass of 79.10 g/mol. To find the actual molecular formula, divide 240, the molar mass of the compound, by 79.10 to obtain 3. So the formula is three times the empirical formula, or C 15 H 15 N 3.
