    In order to calculate for the amount of CaCl2 and water used we need to multiply the total amount mixture to the percentage of each component. Since we are given a two component mixture CaCl2-water with 40% CaCl2 by mass, therefore we have 60% water.

    Amount of CaCl2 = 0.40 * (370.9) = 148.36 g of CaCl2

    Amount of Water = 0.60 * (370.9) = 222.54 g of Water
