  • An empirical formula tells us the relative ratios of different atoms in a compound. The ratios hold true on the molar level as well. Thus, H 2 O is composed of two atoms of hydrogen and 1 atom of oxygen. Likewise, 1.0 mole of H 2 O is composed of 2.0 moles of hydrogen and 1.0 mole of oxygen. We can also work backwards from molar ratios:
