Homework Help: Ochem

Posted by Lindsay on Wednesday, October 19, 2011 at 6:53pm.

A student needed to determine the percent composition of a mixture that contained fluorene and benzoic acid. The student took 283 mg of the mixture and used the extraction method to separate the components. Then both compounds were recrystallized and dried. The experiment produced 141 mg of fluorene and 105 mg of benzoic acid. Calculate the percent composition of the mixture.

Fluorene = _____%
Benzoic acid = ______%


In order to find the percent composition of fluorene, would I just divide 105 by 283 and then multiply by 100 to get the answer?



Any help would be appreciated! :D
