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 1.0g sample?
