Determine the empirical and molecular formula
WebThere are three main types of chemical formulas: empirical, molecular and structural. Empirical formulas show the simplest whole-number ratio of atoms in a compound, … WebMolecular or molar mass (amu or g/mol) / empirical formula mass (amu or g/mol) = n formula units/molecules. The molecular formula is then obtained by multiplying each subscript in the empirical formula by n, as shown by the generic empirical formula AxBy. (A x B y) n = A nx B ny. N, x, and y are subscripts.
