Benzophenone’s chart density of 1.15 g/ml and chart melting point of 48 C were the numbers closest to the numbers I recorded in the lab. Also the fact that it was insoluble in water and soluble in both cyclohexane and alcohol made it the clear choice for my solid.

Chloroforms chart density of 1.49 g/ml may have been a little off what I got in the lab but the boiling point of 61 C on the chart convinced me that it was chloroform. Also the fact that it was insoluble in water and soluble in both cyclohexane and alcohol made it the clear choice....
