Steps to determine an empirical formula of a compound: A. From mass percent. 1. Assume a 100 g sample – use the percent numbers as “grams”. 2. Convert the mass of each element into moles of the element, using a “mass-to-mole” conversion. 3.Divide the resulting number of moles of each element by the smallest number of moles present, to give the ratio of moles in the compound. Express ...
