In a typical experiment, 100 mL of water is placed in the polystyrene foam cup and the initial temperature of the water recorded.5.05 g potassium nitrate, KNO3(s), is added to the water while stirring. The temperature of the solution falls and the minimum temperature acheived is recorded as the final temperature. The results of the experiment are shown in the table below. volume of water =100 mL mass of KNO3(s) = 5.05 g initial temperature = 25.0°C final temperature = 21.7°C. Determine the heat of solution of potassium nitrate.
