8. 9. 10. A solution is prepared by dissolving 27.0 g urea (NH₂)2CO, in 150.0 g of water. Calculate the boiling point of the solution if the Kb of water is 0.50 °C kg/mol. What mass of glycerin (C3H8O3), a nonelectrolyte, must be dissolved in 200.0 g of water to give a solution with a freezing point of -1.50 °C? The Kf for water is 1.86 °C kg/mol. A 0.500 g sample of a compound is dissolved in enough water to form 100.0 mL of solution. This solution has an osmotic pressure of 2.50 atm at 25 °C. If each molecule of the solute dissociates into two particles (in this solvent), what is the molar mass of this solute?
