Stoichiometry

Here, we begin to think about calculations as applied to chemical reactions. In all chemical reactions, there are reactants that break apart and rearrange bonds to make new products, in keeping with the Law of Conservation of Mass. Here, students are looking at calculating the number of moles of a reactant or product given another one. This unpacks the concept of mole ratios and emphasizes that moles are the only mode of conversion in chemistry between different substances.

Learning Goals:

  • To determine the quantities of reactants or products using stoichiometric calculations (gram or mole)
