A 0.194-g sample of a nonvolatile solid solute dissolves in 9.82 g of cyclohexane. The change in the freezing point of the solution is 2.94°C. (Kf of Cyclohexane is 20.0°C/m)
a. What is the molality of the solute in the solution?
b. Calculate the molar mass of the solute to the correct number of significant figures.
c. The same mass of solute is dissolved in 9.82 g of TBA instead of cyclohexane. (Kf of TBA is 9.1°C/m) What is the expected freezing point?
