This lesson defines empirical and molecular formulas and looks at ways of determining them. Combustion is introduced as one method for determining the percent composition of a material. Also, students are shown how to determine the number of waters of hydration in a hydrate.
This lesson is appropriate for AP Chemistry or Honors Introductory Chemistry.
Detailed answer keys are included.
The topics covered include:
-Using Percent Composition
-Empirical and Molecular Formulas
-Using the Molar Mass to Determine the Molecular Formula
-Determining the Molecular Formula
-Applying Combustion Analysis
-Determining the Number of Waters of Hydration
-Practice with Determining the Number of Waters of Hydration
