When 646. mg of a certain molecular compound X are dissolved in 60.0 g of benzonitrile (CH₂CN), the freezing point of the solution is measured to be -13.2 °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 the correct number of significant digits.
