What is the molecular mass of an organic compound if 16.00 g of the compound is dissolved in 225.0 g of carbon tetrachloride raises the boiling point to \( 85.36{ }^{\circ} \mathrm{C} \) ? ebullioscopic constant: \( 5.03{ }^{\circ} \mathrm{C} \mathrm{kg} \mathrm{mol}^{-1} \) boiling point: \( 76.72{ }^{\circ} \mathrm{C} \)

Step 1
\[ \Delta T_b = T_{\text{boiling, solution}} - T_{\text{boiling, pure solvent}} \] \[ \Delta T_b = 85.36^\circ \text{C} - 76.72^\circ \text{C} = 8.64^\circ \text{C} \] Show more…

A 2.00 -g sample of a large biomolecule was dissolved in 15.0 $\mathrm{g}$ carbon tetrachloride. The boiling point of this solution was determined to be $77.85^{\circ} \mathrm{C}$ . Calculate the molar mass of the biomolecule. For carbon tetrachloride, the boiling-point constant is $5.03^{\circ} \mathrm{C} \cdot \mathrm{kg} / \mathrm{mol},$ and the boiling point of pure carbon tetrachloride is $76.50^{\circ} \mathrm{C} .$
