How to calculate the percent yield of a chemical reaction. The percent yield is determined using the following equation. By the definition of percentage yield in chemistry percent yield is said to be percent ratio of actual yield to the theoretical yield.
Calculate the actual yield using the formula above.
Percentage yield of NaCl 850 grams 993 grams 100. Tonstimes 100 64 Due. Multiply the answer that you got in Step 4 by 100 to get your final actual yield. The answer is the theoretical yield in moles of the desired product.
