When 42.5 g of a certain molecular compound X are dissolved in 90. g of benzonitrile (CH,CN), the freezing point of the solution is measured to be -15.8 °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 2 significant digits.
