A certain substance X condenses at a temperature of 90.5 °C. But if a 600. g sample of X is prepared with 35.3 g of urea ((NH,),CO) CO dissolved in it, the sample is found to have a condensation point of 91.2 °C instead. Calculate the molal boiling point elevation constant K, of X. Round your answer to 1 significant digit. 1 °C-mol .kg 1%

Examine the nanoscale diagrams and the phase diagram for Question 112. Match each particulate diagram (1 through 7) to its corresponding point (A through H) on the phase diagram.
A mixture of toluene (bp110.8C) and water is steam distilled. Visual inspection of the distillate reveals that there is a greater volume of toluene than water present, yet water (bp100C) has the higher vapor pressure. Explain this observation.
A solution of benzoic acid in benzene has a freezing point of 3.1 C and a boiling point of 82.6 C. (The freezing point of pure benzene is 5.50 C, and its boiling point is 80.1 C) The structure of benzoic acid is Benzoic acid, C6H5CO2H What can you conclude about the state of the benzoic acid molecules at the two different temperatures? Recall the discussion of hydrogen bonding in Section 11.3.
