Ethylene glycol, HOCH2CH20H, is a common automobile antifreeze. It is water soluble and fairly nonvolatile (boiling point = 197°C). Calculate the freezing point of a solution containing 759 0-g of this substance in 4868 g of water. (Cryoscopic constant of water = 1.86 °C/molal; Atomic Weight: C = 12.01 g/mol; H = 1.008 g/mol; O = 16.00 g/mol). Express your answer in two decimal places. Do not put the units.

Sodium chloride (NaCl) is commonly used to melt ice on roads during the winter. Calcium chloride (CaCl2) is sometimes used for this purpose too. Let us compare the effectiveness of equal masses of these two compounds in lowering the freezing point of water, by calculating the freezing point depression of solutions containing 200. g of each salt in 1.00 kg of water. (An advantage of CaCl2 is that it acts more quickly because it is hygroscopic, that is. it absorbs moisture from the air to give a solution and begin the process. A disadvantage is that this compound is more costly.)
