Abuela asked Mirabel to perform an experiment on freezing point depression. The solution was prepared by dissolving 2.25 g of salt in 20.00 mL distilled water (density = 0.997 g mL1; Tf = 0 °C; kf = 1.86 °C m1). Mirabel determined the freezing point of the solution to be -3.48 °C. She later found out that the salt she used was sodium chloride that was contaminated with potassium chloride. 1. Calculate ATt for the experiment. 2. Calculate the molality of the solution. 3. Calculate the mass of potassium nitrate present in the salt sample.
