When 2.31 g of a certain molecular compound X are dissolved in 50 g of benzonitrile (C6H5CN), the freezing point of the solution is measured to be -13.3 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.
