Question

If you run a particular reaction, and in theory it was supposed to yield 50.0 grams of product, and the percent yield is 75%, how many grams did you actually end up with?

Answer 1

Answer:

37.5 grams

Explanation:

The percent yield shows how much of the reactant have been converted to product. The percent yield is the ratio of actual yield to theoretical yield multiplied by 100%. It is given by the formula:

%yield = Actual yield/ theoretical yield × 100%

Given that theoretical yield = 50 grams and the percent yield is 75%.

Using the formula and substituting:

75% = Actual yield/ 50 g × 100%

75% / 100% = Actual yield / 50 g

0.75 = Actual yield / 50 g

Actual yield = 0.75 × 50 g

Actual yield = 37.5 grams
