a) When 5.14 grams of Magnesium Chloride are added to 50 g of water, what would be the expected boiling point? Assume complete dissociation of the Magnesium Chloride. b) Assuming your calculation above was correct, the actual boiling point of this solution is experimentally determined to be slightly lower. Why does this occur? Explain your reasoning in 2-3 sentences. *Use only constants found in Table 11.2 of OpenStax for any calculations.
