<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 = 
Mass of benzoic acid after purification = 196 mg
To calculate the percentage composition of a substance in a mixture, we use the equation:

<u>For fluorene:</u>

Hence, the percent composition of fluorene is 33.08 %
<u>For benzoic acid:</u>

Hence, the percent composition of benzoic acid is 36.03 %
