3. You are asked to calculate the Kf for t-butyl alcohol (MW = 74.122 g/mol). You gather the following information in your experiment. You weigh out 2.124 g t-butyl alcohol and you determine the freezing point of the solvent t-butyl alcohol is 21.6 °C (freezing point pure t-butyl alcohol). You then add water to the test tube with the t-butyl alcohol and measure the freezing point to be 15.3 °C. What key piece of information are you missing to calculate the Kf?
