Select correct answer. The percent yield (isolation yield) of guaifenesin isolated from a 650 mg tablet containing 400 mg dose of drug, can be expressed as: Group of answer choices

61.5%.

Explanation:

We usually define percentage yield in chemistry as follows;

Percentage yield= actual yield/theoretical yield ×100

In this case we have;

Actual yield of the guaifenesin 400mg

Theoretical yield of the guaifenesin 650 mg

Hence;

Percentage yield of the guaifenesin =

400/650 ×100 = 61.5%

Hence the theoretical yield of the guaifenesin is 61.5%.
