When 4.33 of a certain molecular compound X are dissolved in 30. g of benzene (c,H,), the freezing point of the solution is measured to be 4.5 °C. Calculate the molar mass of x. If you need any additional information on benzene, 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. olo

When 4.33 g of a certain molecular compound X are dissolved in 30. g of
benzene (C,H,), the freezing point of the solution is measured to be 4.5 °C.
Calculate the molar mass of x.
If you need any additional information on benzene, 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.
