Others have their empirical formulas different from their molecular formulas, example, when you see a formula like H 2 O 2, C 2 H 6 and C 6 H 12 O 6, you are looking at a molecular formula, the empirical formula is HO, CH 3 and CH 2 O respectively. Another way to calculate empirical formulas One can calculate the empirical formula from the percent composition Calculating Empirical Formulas The compound para -aminobenzoic acid (an active ingredient in some sunscreens) is composed of carbon (61. 59% nitrogen, and 15. It is able to undergo complete combustion with oxygen gas to form carbon dioxide gas and water. The empirical formula in chemistry provides the relative numbers of each type of atom in a particular molecule. This means that the proportion of molecules of Carbon Dioxide to molecules of water is 1:1 (in other words, there are the same amount of molecules of each) The empirical formula of a compound is only concerned with showing: (1) the elements present. Concept introduction: Empirical formula of a compound represents the smallest whole number relative ratio of elements in that compound. For iso-octane, the empirical formula is C 4 H 9. 011 g/mol = 3.
