Reacting masses a level chemistry
WebIt is calculated from the balanced equation and the reacting masses. The percentage yield compares the actual yield to the theoretical yield. For economic reasons, the objective of every chemical producing company is to have as high a percentage yield as possible to increase profits and reduce costs and waste.
