A 40-year-old manager, at a prominent legal firm in L.A., experiences abdominal pain post lunch. He goes to the restroom a couple of times, but continues to experience pain and cramps. He eventually decides to get himself examined. While questioning him, you learn that he consumed two bottles of beer at lunch. The alcohol (ethyl alcohol/ethanol) content in a 12 oz. bottle of beer is about 5%. The man's weight is 150 lbs and he was drinking over an hour period.

Inorganic Chemistry
A solid mixture consisted of equal parts by weight of benzoic acid, acetanilide and
copper sulfate. 1.80 g of this mixture was dissolved in 110 mL of boiling water and
slowly cooled to 0 °C. Determine the composition and percentage purity of the crystals
that formed. [Solubilities of benzoic acid, acetanilide and copper sulfate at 0 °C are
1.70, 5.30 and 316 g per litre, respectively.]
