Lab Experiment for Stoichiometry! Want to include a lab experiment that correlates with Stoichiometry? This lab report requires students to directly apply their understanding of Empirical Formula and Percent Composition in a practical way! Students will choose one hydrate to use in the lab procedure. Students will be given the formula of the anhydrous form, but the number of water molecules in the hydrate are unknown. Students will be determining the number of water molecules by heating the hydr
