| empirical formula
A chemical formula that indicates the relative proportions of the elements in a molecule rather than the actual number of atoms of the elements. The empirical formula of a compound may be simpler than its molecular formula, which is a multiple of the empirical formula. For example, glucose has the molecular formula C6H12O6 but the empirical formula CH2O. Compare molecular formula, structural formula. |
