WebOct 7, 2014 · You start by determining the empirical formula for the compound. Determine the mass in grams of each element in the sample. If you are given percent composition, you can directly convert the percentage of each element to grams. For example, a molecule has a molecular weight of 180.18 g/mol. It is found to contain 40.00% carbon, 6.72% … WebTo calculate the percent composition, the masses of C, H, and O in a known mass of C 9 H 8 O 4 are needed. It is convenient to consider 1 mol of C 9 H 8 O 4 and use its molar …

WebTo find out what we need to do is to take the molar mass of the molecule and divide it by the empirical formula mass which we can calculate ourselves. Let's calculate it in the problem. The mass of the mole is 78.1 gram per mole. Adding 12.01 for carbon to 1.01 for hydrogen gives us 13.02, which is the empirical formula mass.
