When 236. mg of a certain molecular compound X are dissolved in 70.0 g of benzonitrile (C6H,CN), the freezing point of the solution is measured to be -13.8 °C. Calculate the molar mass of X. If you need any additional information on benzonitrile, use only what you find in the ALEKS Data resource. Also, be sure your answer has a unit symbol, and is rounded to 1 significant digit. 10
