One way to recrystallize a solute from a solution is to change the temperature. Another way is to evaporate solvent from the solution. A 335 g sample of a saturated solution of KNO₃(s) in water is prepared at 25.0 °C. If 55 g H₂O is evaporated from the solution at the same time as the temperature is reduced from 25.0 to 0.0 °C, what mass of KNO₃(s) will recrystallize? (Refer to Figure 14-10.)
