The theoretical yield is what you calculate when you do a calculation on paper or before you do a reaction in a lab. The actual yield will always be less than the theoretical yield because no chemical reaction ever reaches 100 percent completion. In a lab setting, there's always some amount of error, whether it's big or small The equation for percent yield is percent yield = actual yield/theoretical yield x 100%. Let me show you how this works with an actual chemical reaction. Example On The **reaction** **yield** (absolute **yield**) **of** a chemical **reaction** is the amount of pure and dry product yielded in a **reaction**. Normally, in order to measure the efficiency of a chemical **reaction** in organic synthesis, the relative or percentage **yield** (%) is calculated

Theoretical yield formula. Using the theoretical yield equation helps you in finding the theoretical yield from the mole of the limiting reagent, assuming 100% efficiency. 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 In chemistry, yield, also referred to as reaction yield, is a measure of the quantity of moles of a product formed in relation to the reactant consumed, obtained in a chemical reaction, usually expressed as a percentage.
