This unit is not arranged as a traditional stoichiometry unit. Rather than beginning by stating the law of conservation of mass to students, it begins with an inquiry lab for students to discover that law. All quantities in this lab will be measured in grams. This will lead to a discussion of grams versus moles — when each unit is appropriate and why. After students have developed this basic understanding, they will be presented with an in-class lab demonstration and subsequent simulation involving limiting reactants. Limiting reactants will be used to help students understand the most efficient ratios needed in a chemical equation that will produce maximum product. Students use this same logic and apply it in order to balance chemical equations.
