Chemistry - Calculating the Empirical Formula of a Compound!

This video tutorial explains how to calculate the empirical formula of a compound in four steps: percent to grams, grams to moles, divide by small, and multiply to a whole. It begins with an introduction to empirical formulas and their importance, followed by a demonstration of simplifying molecular formulas. Two example problems are provided to illustrate the process, one involving carbon, hydrogen, and oxygen, and the other involving magnesium and nitrogen.
