This chemistry video tutorial explains how to find the amount of excess reactant that is left over after the reaction is complete. You need to start with the limiting reactant and convert that quantity into the grams of excess reactant. This represents the amount of excess reactant that is actually consumed or used up in the reaction. The difference between the starting amount of excess reactant and the amount that is consumed is equal to the amount of excess reactant left over. This chemistry tutorial contains plenty of examples and stoichiometry practice problems.
