how to do percent yield of a reaction. The extent to which a reactions theoretical yield is achieved is commonly expressed as its percent yield. Percent yield actual yield theoretical yield 100 Actual and theoretical yields may be expressed as masses or molar amounts or any other appropriate property.

Percentage yield is a concept used in chemistry which compares the theoretical yield of an experiment with the actual results observed. Eg volume if the product is a gas. Usually the percent yield is less than 100 percent due to inaccuracies in the measurements the reaction not running to completion or a limited availability of one of the reactants.
Percent yield 75g CH 3 OH 1152 g CH 3 OH x 100 65.
Percentage yield fracactual yieldtheoretical yield times 100. I have seen many Grignard reactions performed on the large scaleand in the early days. The percent yield is the ratio of the actual yield to the theoretical yield expressed as a percentage. Percent yield actual yield theoretical yield 100 Actual and theoretical yields may be expressed as masses or molar amounts or any other appropriate property.
