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.
Calculate the yield of each reactant. To review, follow the strategy outlined in How to Calculate Theoretical Yield. The mole ratios between each reactant and the product is needed to complete the calculation: The mole ratio between H 2 and H 2 O is 1 mol H 2 /1 mol H 2 O.The mole ratio between O 2 and H 2 O is 1 mol O 2 /2 mol H 2 O. The molar masses of each reactant and product are also needed.uch more water is formed from 20 grams of H 2 than 96 grams of O 2. Oxygen is the limiting reactant. After 108 grams of H 2 O forms, the reaction stops. To determine the amount of excess H 2 remaining, calculate how much H 2 is needed to produce 108 grams of H 2 O.
