Question

A chemical 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%​

Answer 1

82.11%

Step-by-step explanation:

We are given;

• Theoretical mass of the product is 137.5 g
• Actual mass of the product is 112.9 g

We are supposed to calculate the percentage yield

• We need to know how percentage yield is calculated;
• To calculate the percentage yield we get the ratio of the actual mass to theoretical mass and express it as a percentage.

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 %
