The theoretical yield is a term used in chemistry to describe the maximum amount of product that you expect a chemical reaction could create. How to calculate the percent yield of a chemical reaction. Remember that if the actual and theoretical yield both is the same then the percent yield is 100.
To express the efficiency of a reaction you can calculate the percent yield using this formula.
With these two pieces of information you can calculate the percent yield using the percent-yield formula. 1 The combustion of 0374 kg of methane in the presence of excess oxygen produces 0983 kg of carbon dioxide. Calculating percentage yield The percentage yield is calculated using this equation. How to calculate the percent yield of a chemical reaction.
