- Combustion analysis gives the amounts of carbon and hydrogen in a sample of combustible compound.
- The C forms CO 2 , which is absorbed in the first chamber.
- The H forms H 2O, which is absorbed in the second chamber.
- Weigh the chambers before and after combustion.
- Calculate the masses of CO 2 and H 2O
- Use them to calculate the masses of C and H in the compound.
- From the masses, calculate the empirical formula.
