A solution containing 6.314 g of a non-volatile organic solute dissolved in 100.00 g of toluene boils at 384.72 K at 1 bar of pressure. The boiling point of pure toluene is 383.75 K and AvapH = 38.06 kJ/mol for benzene. (a) What is the boiling point elevation constant for toluene? (units: kg.K/mol) (b) What is the molar mass (g/mol) of the unknown solute?
