Homework Help: Organic Chemistry

Posted by Anna on Tuesday, January 10, 2012 at 9:47pm.

An impure sample contains 0.95g of benzoic acid and 0.05 of salicylic acid. Solubilities in water of the two compounds are given in the following table.
Solubility at 20 degrees (g/10mL)
benzoic acid: 0.029
salicylic acid: 0.22

Solubility at 100 degrees (g/10mL)
benzoic acid: 0.680
salicylic acid: 6.67

--> What is the minimum volume of boiling water needed to dissolve the 1.0 g sample?

I'm not sure on what to do. Do I use the solubilities at boiling point for each to find the volumes and then just add the volumes together?
