Data Sheet sample calculation for the solubility of KNO, using your actual mass from tube #1. Complete gives the recommended mass of salt to dissolve in each of the four test tubes. Show a your graph on the back of this sheet. Solution # Recommended mass KNO, Solubility Actual mass of KNO, (g per 5 ml. H₂O) Saturation. temperature 8 KNO, (g) 100 g H,O (°C) 1 2.0 2.1971 51.3 2 4.0 11.1568 62.5 3 6.0 6.0112 72.7 83.6 4 8.0 8.06 Sample Solubility Calculation: Questions 1. According to your data, how does the solubility of KNO, change with increasi- temperature? Does this indicate an endothermic or exothermic dissolving process? Explain. 2. Using your graph, indicate if each of these solutions would be saturated or unsaturated: a) 110 g of KNO, in 100 g of water at 40 °C b) 60 g of KNO3 in 100 g of water at 70 °C c) 140 g of KNO3 in 100 g of water at 60 °C According to your graph, what mass of KNO3 will dissolve in 100 g of water at 30 °C?
