We have to calculate the molar mass of X.

When 2.78 g of a certain molecular compound X are dissolved in 45.0 g of dibenzyl ether ((CH₂CH₂)₂0), the freezing point of the solution is measured to be 0.9 °C. Calculate the molar mass of X. If you need any additional information on dibenzyl ether, 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. 0 8 D.D 5
