A 544 mg of a mixture of fluorene and benzoic acid was weighed out and subjected to an extraction and recrystallization. After t
butalik [34]

<u>Answer:</u> The percent composition of fluorene is 33.08 % and benzoic acid is 36.03 %.

<u>Explanation:</u>

We are given:

Mass of mixture = 544 mg

Mass of fluorene after purification = 1.80\times 10^2mg=180mg

Mass of benzoic acid after purification = 196 mg

To calculate the percentage composition of a substance in a mixture, we use the equation:

\%\text{ composition of substance}=\frac{\text{Mass of substance}}{\text{Mass of mixture}}\times 100

<u>For fluorene:</u>

\%\text{ composition of fluorene}=\frac{180}{544}\times 100=33.08\%

Hence, the percent composition of fluorene is 33.08 %

<u>For benzoic acid:</u>

\%\text{ composition of benzoic acid}=\frac{196}{544}\times 100=36.03\%

Hence, the percent composition of benzoic acid is 36.03 %
