To determine the freezing points of distilled water, 1m glucose, 1m NaCl, 1m CaCl2. Use the freezing point of the pure water as a baseline to determine deltaTf for each of the solutions (glucose,NaCl,CaCl2) On the basis of these values, calculate the freezing point Coefficient (Kf) for water in each case and compare your average Kf value to the accepted value. This confuses me. I would like to know what to do here. additional info. for calculating molality we used 0,05kg water. So glucose was 180g/mol> 9g NaCl 58.5g/mol > 2.9g CaCl2 147g/mol > 7.4g these are the values we used
