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.  Read More →

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...
