Chemistry

Given the following solubilities in grams/100ml of water (theseare the amounts that stay in solution at these temperatures):

caffeine 1.35g (16 degrees Celcius) 45.5g (65 degreescelcius)

NaCl 35.7g (0 degree celcius) 39.1g (100 degrees celcius)

Suppose that 20g of a mixture that is 75% caffeine and 25% NaClis crystallized from 100mL of boiling water and cooled to 16degrees celcius.

a) how much of the caffeine from this mixture stays in solutionat 16 degrees celcius?

b) what is the most caffeine from this mixture that can beexpected to cystallize?
