A 2g sample of a large biomolecule was dissolved in 15g of 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 x kg/mol, and the boiling point of pure carbon tetrachloride is 76.50 C.
