Question

Is this correct????

A 537 mg of a mixture of fluorene and benzoic acid was weighed out and subjected to an extraction and recrystallization. After this purification was completed the product crystals were dried and analyzed. The purification procedure produced 201 mg of fluorene and 242 mg of benzoic acid. Calculate the percent composition of this mixture. Fluorene Benzoic Acid Number Number 45.06 37.4 Tools x 10

Answer #1

Fluorene percentage = (201 mg / 537 mg) x 100 = 37.4 %

Benzoic acid percentage = (242 mg / 537 mg) x 100 = 45.06 %

Your answer is correct.
