Aug 11, 2011 . In chemistry labs, students are often required to calculate percent yield, which

the theoretical is the maximum that could be obtained assuming all reactants are

Chemists look at the yield of a chemical reaction. Yield consistently means the

Note that the phosphoric acid is a catalyst and is not involved in the yield

Actual yield (or absolute yield) describes the mass or amount of product in the

Percentage yield = (actual yield ÷ theoretical yield) x 100. Optimum yield is the

You learned how to calculate theoretical yield and percent yield in general
