The Rast method uses camphor (C10H160) as a solvent for determining the molar mass of a compound. When 3.26 g of unknown compoud are dissolved in 85.70 g of camphor (Kf = 40.0 °C/m), the freezing point of the mixture is 170.30 °C; that of pure camphor is 178.40°C. What is the molar mass of unknown compound? Express your answer with 4 decimal places.
