16. (Check all that apply) The addition of a soluble, nonvolatile solute to pure water will: increase the vapor pressure decrease the vapor pressure increase the boiling point decrease the boiling point increase the freezing point decrease the freezing point 17. A solution of glucose in water is prepared so that the concentration is 0.25 molal. Write a chemical formula for a compound that, when dissolved in water to give a 0.25 molal solution, would have a freezing point depression three times that of the glucose solution
