Achemical reaction can theoretically produce 137.5 grams of product, but in actuality 112.9 grams are
produced. which is the percent yield for this reaction?
a. 82.11%
c. 24.60%
b. 62.08%
d. 17.91%

82.11%

We are given;

We are supposed to calculate the percentage yield

Thus;

% yield = (Actual mass ÷ Experimental mass) × 100%

            = (112.9 g ÷ 137.5 g) × 100%

            = 82.11%

Therefore, the percentage yield of the product is 82.11 %
