3. What is the solubility of sodium chloride in 100.0 grams of water at 90.0 C?
4. What is the minimum temperature needed to dissolve 180.0 g of potassium nitrate in 100.0 g of water?
5. What is the minimum temperature needed to dissolve 35.0 g of potassium chloride in 100.0 g of water?
6. At what temperature do potassium chloride and potassium nitrate have the same solubility?
7. How much more potassium chloride will dissolve at 90.0 C than at 20.0 C?
8. If 50.0 g of sodium chloride is mixed with 100.0 g of water at 80.0 C, how much will not dissolve?
