The key to empirical formulas is finding the simplest whole-number ratio of atoms in a compound. Start by listing the subscripts of each element in acetic acid, then divide all of them by their greatest common divisor—this strips away any repetition and reveals the most reduced form. Think of it like simplifying a fraction: you're looking for the smallest set of integers that captures the same elemental proportions.
