WebJul 21, 2024 · 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 H2O is composed of 2.0 moles of hydrogen and 1.0 mole of oxygen. WebThe ratio should be close to 1:1 as the formula of magnesium oxide is MgO. Example calculation: Mass magnesium = 2.39 g Mass magnesium oxide = 3.78 g So mass oxygen = 1.39 g Number moles Mg = 2.39/24 = 0.0995 Number moles O = 1.39/16 = 0.0868 Divide by the smallest to give the ratio aproximately 1 Mg : 1 O
