One way to recrystallize a solute from a solution is to change the temperature. Another way is to evaporate solvent from the solution. A 340 g sample of a saturated solution of KNO3 in water is prepared at 25.0.
If 60 g H2O is evaporated from the solution at the same time as the temperature is reduced from 25.0 to 0.0, what mass of KNO3 will recrystallize?
