This chemistry video tutorial shows you how to determine the empirical formula from percent composition by mass in grams. This video also shows you how to determine the molecular formula from the empirical formula using the combustion analysis technique of a compound. This video contains plenty of examples and practice problems that can help you on your next upcoming worksheet assignment / quiz.
Here is a list of topics:
1. Empirical Formula - Lowest Whole Number Ratio
2. Finding the empirical formula from mass in grams
3. Determining the empirical formula using percent composition by mass
4. Calculating Molecular Formula From Empirical Formula Using Molar Mass
5. Combustion Analysis - Compound with 2 elements - Carbon & Hydrogen
6. Empirical Formula From Combustion Analysis - 3 Element Compound - Carbon, Oxygen, and Hydrogen
7. Decimal Ratio Subscripts & Fractions - Converting to whole numbers
