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 mL; Tr = 0 °C; kr = 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 AT: for the experiment. 2. Calculate the molality of the solution. 3. Calculate the mass of potassium nitrate present in the salt sample.
