(Answered) Pure ethanol boils at 78degc but an ethanol solution

Academics

Pure ethanol boils at 78°C, but an ethanol solution containing glycerol (condensed formula: CH2(OH)CH(OH)CH2(OH)) does not. If 4.66 g of glycerol has been dissolved in 125 g of ethanol:

a. What is the molality of the solution?

b. At what temperature does the solution begin to boil? (Kb = 1.22°C /m)
