Whichever reactant results in the smallest amount for the product is the limiting reactant, and the number itself is the theoretical yield. The theoretical yield is the maximum amount produced from a balanced chemical equation based on 100% efficiency. The actual yield is the amount that is actually produced in lab. To find the percent yield, divide the actual yield by the theoretical yield and multiply that by one hundred. In this lab we will use the steps listed above to find the mass of the precipitate is formed from a double replacement chemical reaction. The two reactants chosen for the lab are Lead (II) Nitrate and Sodium Sulfate which produces a precipitate, Lead (II)
