A reaction of 7 .0g Cl 2 with 2 .3g P 4 yields 7 .1g PCl 5 . The percent yield of product formed in the reaction has to be calculated. Concept Introduction: The mass of a product isolated from a reaction is known as the actual yield. The actual yield of a product, the result of a laboratory experiment is less than the theoretical yield and is expressed as percent yield. Limiting reactant: Limiting reactant is the one that yields the smallest amount of any one product. If the mass of more than one reactant is given, approach the stoichiometry problem by calculating the number of moles of product formed from the quantity of each reactant. The reactant that yields the smallest amount of product is limiting; use it for the stoichiometry calculation.
