The freezing point of a cyclohexane sample is 6.20 °C. A solution is prepared by dissolving 0.4660 g of an unknown solute in 36.0 g cyclohexane. The freezing point of the solution is 4.11 °C. (a) Calculate the molar mass, Mm, of the unknown solute below. [kr for cyclohexane is 20.0 °C-kg/mole] (b) The freezing point depression constant, k₁, depends on the solvent, solute or both. [circle your answer] (c) The relationship between AT, and molar mass of a solute is such that as AT, increases, the molar mass increases, decreases, stays the same [circle your answer].
