To solve this problem we need to use the concept of Boiling point Elevation. This is basically when the boiling point of the solution increases with the addition of a solute. The change in boiling temperature (ΔT) can be solved using the formula below:
A 2.00-g sample of a large biomolecule was dissolved in 15.0 g carbon tetrachloride. The boiling point of this solution
was determined to be 77.85°C. Calculate the molar mass of the biomolecule. For carbon tetrachloride, the boiling-point constant is 5.03°C/m , and the boiling point of pure carbon tetrachloride is 76.50°C.
