27. Solving a chemistry problem

2. The molar mass of the lipid is determined by the increase in boiling point. The lipid can be dissolved in methanol or chloroform. The boiling point of methanol is 64.7 C. The heat of vaporization is 262.8 cal*g-1. The boiling point of chloroform is 61.5 C. The heat of vaporization is 59.0 cal*g-1 Calculate the ebullioscopic constants of methanol and chloroform. What is the best solvent to use. to determine the molar mass with greater accuracy?
