Substituting the input values we have the equation as such We know the formula to calculate Percent Yield = (Actual Yield/Theoretical Yield)*100% What is the percent yield of this reaction? Question 2: During a chemical reaction 2.7 g of product is made. Substituting the input values we have the equation as follows We know the formula to calculate Percentage Yield = (Actual Yield/Theoretical Yield)*100% Question 1: If the percentage yield is 55% with the theoretical yield as 6g, what would the actual yield be? Calculate using the percentage yield formula. Multiply the result obtained in the earlier step with 100 to determine the Percentage Yield.Now divide the experimental yield value with the theoretical yield value.The first and foremost step is to make sure both the weights are in the same units.Go through the step-by-step guide provided here to find the Percentage Yield. Theoretical yield - it is the amount of product you get from the stoichiometric or balanced equation, y making using of the limiting reactant to determine the productīy now, you might have understood that in order to obtain the Percent Yield you need both the actual yield and theoretical yield of your reactants.Actual yield - It is the amount of product you get in a chemical reaction.Percent Yield = Actual Yield/Theoretical Yield * 100 In the case of actual yield and theoretical yield being the same, the Percent Yield would be 100%. Percent Yield can be found by simply dividing the experimental yield or actual yield with the theoretical yield and then multiplying with 100. However, it can be greater than 100% at times indicating more sample was recovered from a reaction than the initial predicted yield. Percent Yield in general is lower than 100% as the actual yield we obtain after a reaction is always less than the theoretical value.

In chemistry, percent yield is defined as the ratio of experimental yield to theoretical yield.

In simple words, it tells us how well we performed a chemical reaction. Percent Yield is nothing but the measure of a synthetic procedure's effectiveness.
