In performing 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-1; Tf = 0 °C; kf = 1.86 °C m-1). We determined the freezing point of the solution to be -3.48 °C. We later found out that the salt we used was sodium chloride that was contaminated with potassium chloride. Calculate ΔTf for the experiment.
