How much KNO3 remains dissolved in solution at 0 °C? Answer: 4 g potassium nitrate + How much KNO3 would crystallize out of the solution at 0 °C? Remember, if there is too much of a substance for it all to dissolve, the remainder must crystallize out. Answer: 32 g potassium nitrate + How much CUSO4•5H2O would crystallize out of the solution at 0 °C? Remember, if there is too much of a substance for it all to dissolve, the remainder must crystallize out. Answer: g copper(II) sulfate pentahydrate + What percentage of the KNO3 in the sample is recovered as solid crystals at 0 °C? Answer: 78 % Check
