a chemical formula which gives the composition of elements in a molecule in their lowest relative proportions but does not specify the structural arrangement or true molecular weight (Ex.: CH for benzene or acetylene)
Empirical formula. (n.d.). In YourDictionary. Retrieved from https://www.yourdictionary.com/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.
