Using the data you have collected for Part II of the experiment, complete the following table. For the freezing point depression calculation, be sure to use the average value for the freezing point of pure water and the value for the molality of the solution that you entered earlier. Trial # Tf (ave), pure H₂O (°C) Unrounded ● Temperature values should be entered in to nearest 0.1 °C. Tf, NaCl (aq) (°C) Freezing Point Depression of NaCl (aq) (AT) (°C) Unrounded Rounded Freezing Point Constant of Water, Kf (°C/m) Unrounded Rounded
