Dave performs an experiment to determine the van 't Hoff factor for an aqueous solution of CaCl2. He adds 0.736 g of CaCl2 to the sample test tube along with 20.0 mL of distilled water. He then freezes the solution and determines the freezing point depression from the difference in melting point of the pure solvent and the solution. He obtains 1.8 °C as the freezing point depression, ∆T, for his first trial and 1.7 °C in his second trial. What is the calculated van 't Hoff factor using Dave's experimental data? Molar mass of CaCl2 is 110.98 g/mol Density of H2O is 0.9982 g/mL Kf of water is 1.86 °C/m
