New AP & General Chemistry Video Playlist - Empirical Formula & Molecular Formula Determination From Percent Composition

This chemistry video tutorial explains how to find the empirical formula given the mass in grams or from the percent composition of each element in a compound. If you're given the mass percent, you can simply treat it as if you were given the mass in grams. This video explains how to find the molecular formula given the molar mass of the compound. You can do this once you have the empirical formula. This video explains all of it. It has plenty of practice problems and examples for you to master this lesson.
