Freezing Point Depression

Q. Sodium chloride is commonly used to melt ice on roads during the winter. Calcium chloride 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 170. g of each salt in 1.00 kg of water.
