What is the term for the ratio of actual yield to theoretical yield, multiplied by 100?

Explanation:
The concept here is quantifying how efficiently a chemical reaction proceeds by comparing what was actually obtained to what could have been obtained in principle. The term for the ratio of actual yield to theoretical yield, multiplied by 100, is percent yield. In practice, you first determine the theoretical yield from the balanced equation using stoichiometry and the amounts of reactants you started with, assuming the reaction goes to completion. The actual yield is what you recover from the experiment. Percent yield shows how close you came to the ideal amount. For example, if theory predicts 12 g of product but you only obtain 9 g, the percent yield is (9/12) × 100 = 75%. Other options are not about this concept: the ideal gas law (PV = nRT) relates pressure, volume, temperature, and amount of gas; standard temperature and pressure (STP) is a reference condition for gases; and Boyle’s Law describes how pressure and volume of a gas change at constant temperature.
