You weight out exactly 1.00 mg of benzoic acid and dissolve it in a mixture of 2.0 mL of diethyl ether and 2.0 mL of water. After mixing and allowing the layers to separate, the ether layer is removed, dried, and concentrated to yield 0.68 mg of benzoic acid. What is the Kp value (ether/water) for this system?

A 577 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 247 mg of fluorene and 167 mg of benzoic acid. Calculate the percent composition of this mixture. Fluorene Benzoic Acid Number Number 0 0

8A student is given a solution of 20 ml. of ether, which contains benzoic acid and benzocaine. The student uses 5% NaOH to separate the benzoic acid from the benzocaine benzocaine is expected to remain in the organic layer (ether layer). After drying the organic layer, and removing the diethyl ether using a rotavapor, the student finds no benzocaine in the RBF. The student performed the experiment exactly, and no equipment was malfunctioning mechanistic force to help explain!l The Where...
