. A solution of 12.0 g of a nonvolatile, nondissociating compound dissolved in 0.200 kg of benzene boils at 81.2 °C. Calculate the molecular weight of the compound. (boiling point or Tb of pure benzene: 80.1 °C, ebullioscopic constant for benzene: 2.53 °C/m) . A solution contains 23.6 g of a nonelectrolyte and 175 g of water. The water freezes at -7.18° C and Kf = 1.86° C/m. Is the nonelectrolyte CH3OH or C2H5OH?
