D. Rice is difficult to cook at high altitudes due to the lower pressures. Use this fact to answer the
following questions. (4 points)
į. What does the lowered pressure do to the boiling temperature of water? (1 point)
ii. What would adding salt to the water do to the boiling temperature? (1 point)
111. The equation that describes the change in temperature of a solvent due to a solute is
Als = į Kila * molality. How much salt would one need to add to 1 kg water to change the
0.51°C
boiling temperature by 5°C? Give your answer in moles. Show your work. (Kn= (moVkg)) for
water and į = 2 for NaCl.) (2 points)
