Explanation:
Detailed explanation-1: -The equation for percent yield is percent yield = actual yield / theoretical yield x 100%.
Detailed explanation-2: -The actual yield is the amount of product that is actually formed when the reaction is carried out in the laboratory. The percent yield is the ratio of the actual yield to the theoretical yield, expressed as a percentage.
Detailed explanation-3: -Usually, percent yield is lower than 100% because the actual yield is often less than the theoretical value. Reasons for this can include incomplete or competing reactions and loss of sample during recovery.
