To calculate the theoretical yield of any reaction, you must know the reaction. Another example would be if you had 5 rings but you regrettably lose one. Theoretical yield will be calculated in grams because it uses the theoretical yield equation and it is the amount of the expected product. Sample Calculation: The Theoretical yield and Percent yield for Caffeine. The theoretical molar yield is 2.0 mol (the molar amount of the limiting compound, acetic acid). Both the calculations are different in their own uniqueness of calculating method; the exact same goes for the answers each yield obtains. It's also possible for the actual yield to be more than the theoretical yield. Theoretical Yield Formula Questions: 1. Theoretical yield of NaCl in grams = 9.93 grams. Assuming that the reaction will go to completion we can predict this amount of product from the stoichiometric coefficients of the balanced chemical equation. So, to stop you from wondering how to find theoretical yield, here is the theoretical yield formula: mass of product = molecular weight of product * (moles of limiting reagent in reaction * stoichiometry of product) Your actual yield is then the yield you get from the reaction divided by the theoretical yield. The amount of product calculated in this way is the theoretical yield, the amount obtained if the reaction occurred perfectly and the purification method were 100% efficient. Theoretical yield is the quantity of a product obtained from the complete conversion of the limiting reactant in a chemical reaction. Worked example If heated, calcium oxide decomposes to form calcium oxide and carbon dioxide. Using the theoretical yield equation helps you in finding the theoretical yield from the mole of the limiting reagent, assuming 100% efficiency. A more accurate yield is measured based on how much product was actually produced versus how much could be produced. Theoretical Yield Formula The quantity of a product that is released from the reaction is usually expressed in terms of yield. Theoretical yield is a very simple concept. Theoretical yield formula.
