We wish to lower the freezing point of the water in an automobile radiator to -40 °C. The total mass of water present is 12.0 kg. For which one of the following compounds would we have to use the greatest mass of solute to achieve this? You may assume that Kf for water = -1.86 °C/m and that all ionizable solutes are completely ionized with unit activity even at this high concentration. A) AlF3 (M.W. = 84 g/mol), i = 4 B) C2H5OH (M.W. = 46 g/mol), i = 1 C) CaCl2 (M.W. = 111 g/mol), i = 3 D) C3H6(OH)2 (M.W. = 76 g/mol), i = 1 E) NaCl (M.W. = 58.5 g/mol), i = 2
