  1. This is a limiting reagent problem. I know that because BOTH reactants are given. I solve these by solving two simple stoichiometry problems (simple meaning they are NOT limiting reagent problems); one for one reactant and another for the other reactant. Here is an solved example of a simple stoichiometry problem. Just follow the steps. Remember moles = grams/molar mass or moles = M x L.
