How Do You Find Theoretical Yield? | Reference.com
This smallest yield of product is called the theoretical yield. To find the limiting reagent and theoretical yield, carry out the following procedure: 1. Find the moles of each reactant present. 2. Calculate the moles of a product formed from each mole of reactant. 3. Identify the reactant giving the smaller number of moles of product.
How to determine concrete yield
To determine the percent yield: Divide the actual yield made in the lab by the calculated theoretical amount, and multiply by 100. For a synthesis – to find the overall percent yield, multiply the individual percent yields of every step by each other (ex. 3 steps, all 30% yield – 0.30 x 0.30 x 0.30 = 0.27

The goal is to determine the theoretical yield and then the percent yield of the product. For simplicity sake, the reactants and product will be referred to by their nicknames: HYD = NiCl 2 6H 2 O EN = H 2 NCH CH NHTRIS = [Ni(H ) 3]Cl 1. In order to calculate the theoretical yield, you must first determine whether HYD or TRIS is the limiting ...
