WebAug 2, 2024 · The empirical formula is also known as the simplest formula in chemistry. It gives the smallest whole number ratio of elements in a compound using subscripts following element symbols. In some cases, the empirical formula is the same as the molecular formula, which gives the actual number of atoms in a compound (e.g., H 2 O). Webmass = moles × mass of 1 mole. and since mass of 1 mole of a substance (in grams) = molar mass (in grams per mole) mass (g) = moles × molar mass (g mol -1) m = n × M.
