7. Camphor (C10H160) freezes at 179.8°C, and it has a particularly large freezing point depression constant, Kf= 40.0 °C/m. When 0.186 g of an organic substance of unknown molar mass is dissolved in 22.01 g of liquid camphor, the freezing point of the mixture is found to be 176.7°C. What is the molar mass of the solute?
