Which statement best relates an empirical formula with a molecular formula?

An empirical formula gives the simplest whole-number ratio of atoms in a compound. A molecular formula is a whole-number multiple of that ratio, so knowing the empirical formula and the compound’s molar mass can be used to determine its molecular formula. For example, an empirical formula of CH₂O can correspond to a molecular formula of C₆H₁₂O₆.
