Empirical Formulae from Percentage Composition

Empirical Formulae from Percentage Composition If you're given the Percent Composition of a compound, you can find the Empirical Formula for it. I have the shortest method ever to do it, although it's not a "full solution" like your teacher probably asks for. 1. Divide each % by the atomic mass of the element 2. Divide each of THOSE answers by whatever's smallest 3. Adjust these numbers into their lowest whole-number ratio. I hope the video helps :)
