1) Using Figure 1, determine: a. the number of grams of KNO, which will dissolve in 100 g of H₂O at 100°C b. the number of grams of water which are required to dissolve 25 g of KNO, at 100°C c. the number of grams of water which are required to dissolve 2.0g of CuSO,5 H₂O at 100°C d. the number of grams of water which are required to dissolve a mixture of 25 g of KNO, and 2.0g of CuSO45 H₂O at 100°C 2) Take the solution to problem 1d, add 10 mL of deionized water, and cool the solution to 0°C. a. How much KNO, remains in solution? b. How much KNO, crystallizes out? c. How much CuSO,5 H₂O crystallizes out? d. What percentage of KNO, is recovered from the original 25 grams?
