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.

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

From You have a mixture of benzoic acid, hexamethylenediamine, and 1-octanol dissolved in diethyl ether. You wish (for some reason) to separate these compounds and have pure samples of each. Devise a liquid-liquid extraction protocol that would allow you to do this. (up to 20 points) Your answer should be clear and concise. Ambiguous answers or those that are difficult to read will NOT receive points. Search entries or author Unread Subscribe Reply

1. Can benzoic acid be recrystallized using Dichloromethane as a solvent instead of Water. Justify your answer. 2. Benzoic acid purified using recrystallization melted at 10 oC less than its actual M.P. Is the sample pure? List possible errors that could have happened during the recrystallization. 3. Where in the IR spectrum of benzoic acid would you expect to find the C=O and C=C bond?
