Stoichiometry
We have 16 ready-to-use problem sets on the topic of Stoichiometry.
These problem sets focus on the use of the coefficients of a balanced chemical equation and molar mass values to relate the amount of reactants and products involved in a chemical reaction. Problems will range from the very easy mole-to-mole calculations to the more difficult limiting reactant problems.
Problem Sets
Set ST1: Introduction to Stoichiometry
