Limiting Reactants (Reagents)

Limiting Reactants (Reagents). and Percent Yield. Calculations need to be based on the limiting reactant. Example 1: Suppose a box contains 87 bolts, 110 washers and 99 nails. How many sets of 1 bolt, 2 washers and 1 nail can you use to create? What is the limiting factor?
