How to Find the Empirical Formula from Percent Composition

You can find the empirical formula of a compound using percent composition data. If you know the total molar mass of the compound, the molecular formula usually can be determined as well. The easiest way to find the formula is: Assume you have 100 g of the substance (makes the math easier because everything is a straight percent).

How to Calculate the Empirical Formula of a Compound

If you don’t know the empirical formula of a compound, you can analyze samples of the unknown compound to identify the percent composition. From there, you calculate the ratios of different types of atoms in the compound. You express these ratios as the empirical formula.

Enter the atomic symbols and percentage masses for each of the elements present and press “calculate” to work out the empirical formula. If the data does not fit to a simple formula, the program will attempt to generate possible empirical formulae and will indicate how well these fit the percentage composition using the variance.
