In this activity we will investigate why tap water boils faster than the salt solution by computing the boiling point elevation and freezing point depression of the solution. Assume that the boiling point of water is 100 degrees celcius and 3 tablespoon of sodium chloride (salt) and 1 cup of water is approximately 54g and 274mL, respectively. (Density of water is 1g/mL).
