Calculate Vapor Pressure Depression Glucose and CaCl2 Solutions
Question
A. 10.0 g sample of the solid sucrose ( sugar, C12H22O11) was dissolved in 200.0 g of water. What will the vapor pressure of this solution be at 25C, if the normal vapor pressure of pure water at 25C is 23.8 torr?
B. Predict the vapor pressure of a solution prepared by dissolving 49.4 g of solid calcium chloride, CaCl, in150 g of water at 25C. The vapor pressure of water at 25C is 23.8 torr.

Boiling Point Elevation and Freezing Point Depression Question?
Question
Calculate the boiling point and freezing point of the following. 3m of sugar water, 3m of Lithium nitrate, 3m of lead (II) chlorate and 3m of ammonium phsphate.
Answer:
When a solute is dissolved in a solvent, the freezing point of a solution is lowered according to the equation:
^Tf = i•Kf•m
and the boiling point of a solution is elevated according to the equation:
^T = i•Kb•m
where;
^Tb...
