Associated Calculations

There are a number of calculations (other than mole-gram conversions) that are associated with moles and molecular weights. We will look at several of them in the pages of this section. The first deals with determining the molecular weight of a chemical when you do not know its molecular formula. That is what you will be doing in your lab work for this lesson. The next two deal with formulas and composition. One considers determining the composition from the formula and the other considers determining the empirical formula from the composition. The last deals with using the composition and/or empirical formula along with the molecular weight to determine the molecular formula.
