Stoichiometry Tutorials: Part 12 - Determining the Empirical Formula from an Elemental Analysis (from a complete OLI stoichiometry course)

On another page, we discuss how to obtain the empirical formula from a given molecular formula. Here, we consider how to obtain the empirical formula from an elemental analysis of a sample. Remember that comparing the empirical formula obtained from an elemental analysis with that from a molecular formula tells us if the sample is consistent with the molecular formula.
