Question
A 0.85-g sample is dissolved in 0.150 kg of bromobenzene. Determine the molar mass of the solute if the solution boils at 429.0 K at 1 atm pressure. The normal boiling point of bromobenzene is 428.1 K and the ebullioscopic constant is 6.26 K kg mol-1.

deltaT=6.26(.85/molmass)/.240
detat T= 429.0 K -428.1 K
solve for molmass
