A solution is comprised of 19.30 g of Calcium Chloride (CaC2, M = 110.98
g/mol) in 50.0g of ethanol. Ethanol has a density of 0.789 g/mL, and the normal freezing point is -114.10 °C and normal boiling point is 78.37
Calculate the concentration (in molality) of this solution. (3 pts.)
b) Calculate the freezing point depression (in °C) of this solution. The Kof ethanol is 1.99 °C/m. Calculate to two decimal places. (5 pts.)
c) Calculate the new final freezing point of the solution. (2 point)
