error in calculation or your final product is impure and has residuals of chemicals that were supposed to dissappear
Do you need it? Are you being told to calculate it? percent yield = (actual yield) divided by (theoretical yield) x 100
a percent yield will be above 100 if the product used are wet or more likely impure.
45% according to 'on cooking' but I'm confused
Ten percent of 315,000 is 31,500. Simple math will yield 283,500 as the difference.

Percent Yield.
Percentage yield = (Actual yield / Theoretical yield) x 100% The percentage yield for a reaction is a value between 0 to 100 percent.
Percentage yield is calculated by dividing the actual yield of a chemical reaction by the theoretical yield, and then multiplying by 100 to get the percentage. The formula is: Percentage Yield = (actual yield / theoretical yield) x 100%.
It would probably have to be 'percentage yield' in order to use it, for instance: "Our annual percentage yield has dropped significantly over the past decade." or "The percentage yield alone isn't enough to maintain this business."
Experimental yield and actual yield refer to the same thing, which is the amount of product obtained from a chemical reaction in a laboratory setting. Percent yield, on the other hand, is a measure of the efficiency of a reaction and is calculated by comparing the actual yield to the theoretical yield.
Stoichiometry can determine the theoretical yield of CaSO4 by calculating the ratio of reactants and products in a balanced chemical equation. The actual yield can then be compared to the theoretical yield to determine the percent yield of the reaction.
The overall percent yield can be found by converting the individual percentages to decimals (by dividing the percentages by 100), multiplying these decimals together, and converting this product back to percentage. 0.95 X 0.91 X 0.93 = 0.80 or 80 percent yield overall.
You did something wrong in your calculation or you have some impurity. You never get 100% yield.
The process you are describing is known as calculating the percent yield. It is a measure of how efficient a chemical reaction is by comparing the actual amount of product obtained (actual yield) with the maximum possible amount that could be obtained (theoretical yield) under ideal conditions.
Percent yield is calculated by dividing the actual yield (the amount of product obtained in a chemical reaction) by the theoretical yield (the amount of product that should be obtained according to stoichiometry) and multiplying by 100 to get a percentage. This formula allows you to determine how efficiently a reaction was carried out by comparing the actual yield to the maximum possible yield.
Percentage yield is purely for an economic view, you dont want to waste chemicals. purity is for reputation of a drug. impurities have negative effects and decrease potency of a drug.
