Problem 104AE
Carbon disulfide (CS2) boils at 46.30 °C and has a density of 1.261 g/ml. (a) When 0.250 mol of a nondissociating solute is dissolved in 400.0 ml_ of CS2, the solution boils at 47.46 °C. What is the molal boiling-point-elevation constant for CS2? (b) When 5.39 g of a nondissociating unknown is dissolved in 50.0 ml of CS2, the solution boils at 47.08 °C. What is the molecular weight of the unknown?
