A 0.442 g sample of a nonvolatile solid solute dissolves in 15.0 g of t-butanol. The freezing point of the solution is 23.9 degrees Celcius. What is the molality of the solute in the solution. Calculate the molar mass of the solute. The same mass of solute is dissolved in 15.0 g of cyclohexane instead of t-butanol, What is the expected freezing point change of this solution?
