A Solution is prepared by dissolving 50.0g of glucose, C6H12O6, in 400.0g of water. Glucose is a nonvolatile molecular compound. Use this solution to answer three questions below:
1. Calculate the vapor pressure of this solution at 25.0 degrees C. At this temperature, the vapor pressure of pure water is 23.8 mmHg.
2. Calculate the change in the freezing temperature for this solution (Kf=1.86 degrees C/m for water)
3. Calculate the boiling point of this solution (Kb=0.52 degrees C/m for water)
