Question:

In the winter of 1994, record low temperatures were registered throughout the United States. For example, in Champaign, Illinois, a record low of 229oF was registered. At this temperature can salting icy roads with CaCl2 be effective in melting the ice?
a. Assume that i = 3.00 for CaCl2.
b. Assume the average value of i from Exercise 86. (The solubility of CaCl2 in cold water is 74.5 g per 100.0 g of water.)
Value of i in exercise 86
i = 2.57
