![]() As a result, the mole ratio of the two is one. Step 2: Calculate the mole ratio of aspirin to salicylic acid: One mole of salicylic acid was required for every mole of aspirin produced.MM of Salicylic Acid = (7 x 12 g) + (6 x 1 g) + (3 x 16 g) Step 1: Determine the aspirin and salicylic acid molar masses.The stepwise mechanism is mentioned below: The theoretical yield is derived by multiplying the product's number of moles by the product's molecular weight after determining the number of moles, the limiting reagent, and the ratio.Īns.Without computing yield, evaluating the efficiency of reactants would become impossible. It is impossible to predict the outcome without first calculating them. In chemistry, both theoretical and actual yields have a crucial role to play.The actual yield/theoretical yield ratio is used to calculate the percent yield.The actual yield is commonly represented as a percent yield, indicating how close the actual yield was to the anticipated yield. The actual yield is always lower than the predicted yield. In a chemical reaction, the real yield is what you obtain.The theoretical yield is what you get when you use a balanced chemical process to determine the yield.The limiting reactant (or limiting reagent) is the first reactant to be consumed in a chemical reaction, limiting the amount of product that can be created.Multiply the moles of each product by its molecular weight to get the grams of product.This tells you how many moles each product has. Multiply the moles of the limiting reactant by the ratio between the moles of the limiting reactant and the product from the balanced equation once you've identified the limiting reactant.To determine which is accessible in excess and which will be used up first, compare this to the molar ratio of the reactants (the limiting reactant). ![]()
