The Empirical formula is the lowest whole number ratio of the atoms of the elements in a compound. In this video, we show you how to calculate the empirical formula given the percent composition of a compound. We also talk about how the empirical formula and molecular formula are related. We’ll be covering molecular formulas in more depth in another video.
Stay tuned! We'll be adding additional learning resources very soon.
Stay tuned! Bonus features for this video are under development...
Our Chemistry Lessons playlist gives you practical help for the topics that chemistry students often struggle with. Each video has multiple example problems worked out in full. Topics covered include: Balancing Chemical Equations, the MOLE, Gas Laws, Molar Mass, and more.
