3. A reaction produces 14.2 grams of a product. The theoretical yield of that product
nlexa [21]

A reaction that produces 14.2 grams of a product and the theoretical yield of that product is 17.1 grams is true for the following statements :

The percent yield of the product is 83.0%

The actual yield of the product is 14.2 grams.

<h3>Percentage Yield:</h3>

Percent yield is the percent ratio of actual yield to the theoretical yield.

Mathematically,

percent yield = actual yield / theoretical yield x 100%

actual yield = 14.2 grams

theoretical yield = 17.1 grams

percentage yield = 14.2 / 17.1 × 100%

percentage yield = 83.0409356725 %

percentage yield = 83.0 %

Therefore,

The percent yield of the product is 83.0%

The actual yield of the product is 14.2 grams.
