http://www.csun.edu/~hcchm001/IntroChemHandouts.html. A limiting reagent is a chemical reactant that limits the amount of product that is formed. The limiting reagent gives the smallest yield of product calculated from the reagents. (reactants) available. This smallest yield of product is called the theoretical yield.
3. Calculate the percent yield. Divide the actual yield by the theoretical yield, then multiply by one hundred. The answer will be a percent which represents the mass of your product compared to the mass of product from a perfect reaction.. Calculate the amount (in moles) of each reactant. To do this, divide each reactant's mass by its molar mass. 1  To calculate a molecule's molar mass, add the atomic masses of each atom in the compound.
