WebJul 26, 2024 · The formula for percent yield is: (Actual Yield / Theoretical Yield) X 100 = Percent Yield. Percent yield is used in chemistry to evaluate how successful a chemical reaction was in reality, compared to the maximum result expected. Percent yield can also be used by different disciplines when comparing actual results to expected results. Webpercent yield = actual yield theoretical yield × 100 % Actual and theoretical yields may be expressed as masses or molar amounts (or any other appropriate property; e.g., volume, if …
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. Yield is one of the primary factors that scientists must consider in organic and inorganic chemical synthesis processes.
