simplest formula. Compare with molecular formula. Empirical formulas show which elements are present in a compound, with their mole ratios indicated as subscripts. For example, the empirical formula of glucose is CH
2O, which means that for every mole of carbon in the compound, there are 2 moles of hydrogen and one mole of oxygen.

In chemistry, the empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. A simple example of this concept is that the empirical formula of hydrogen peroxide, or H2O2, would simply be HO. An empirical formula makes no reference to isomerism, structure, or absolute number of atoms. The empiric...
