In lecture, we learned the difference between empirical formulas and molecular formulas. An empirical formula is the lowest whole number ratio of elements in a compound. A molecular formula however is a whole number multiple of the empirical formula. An introduction on the two types of formulas can be found by clicking this link. This includes empirical formulas, molecular formulas, mole fractions, thermodynamic calculations and kinetics calculations. Finally, students should also create a study guide for the many laws taught in their AP Chemistry class. Examples of laws to study are Faraday’s law of electrolysis, gas laws, Dalton’s law and Graham’s law.

If the compound has a molar mass of 90.0 g mol-1, what is the molecular formula of this compound? 1. Determine the molar mass of the empirical formula. 12.01 g mol-1 + 2(1.008 g mol-1) + 16.00 g mol-1 = 30.02 g mol-1 2. Divide the molar mass of the molecular formula by the molar mass of the empirical formula. 90.0 30.02 = 3 C 3 H 6 O 3
Sep 11, 2010 · 63.68 g C / 12.011 g/mole = 5.302 mole C atoms. 12.38 g N / 14.0067 g/mole = 0.8839 mole N atoms. 9.80 g H / 1.0079 g/mole = 9.723 mole H atoms. 14.14 g O / 15.9994 g/mole = 0.8838 mole O atoms.... The molecular formula may be a multiple of that and requires the molecular mass be determined. For instance, hydrogen peroxide has the empirical formula HO. Its molecular mass, however, is 34, which corresponds to a molecular formula of H2O2. Example 1: One simple (but expensive) experiment is determining the empirical formula of silver chloride.
