Chemistry in a Nutshell

Empirical and molecular formulas both describe chemical compounds, but they’re not the same! In this video, we compare the two, explain when each is used, and show how to determine a molecular formula from an empirical formula using molar mass. Includes worked examples for clarity! Practice Problems included!
