A 2.30-g sample of a large biomolecule was dissolved in 25.0 g 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 · kg/mol, and the boiling point of pure carbon tetrachloride is 76.50°C.
