A solution contains 35.0g of glucose, C6H12O6, dissolved in 500g ofwater at 40 Celsius. The vapor pressure of water at 40 Celsius is55.3 mmHg.
Calculate the vapor pressure of the solution. (assume glucose is anonvolatile solute.) And calculate the boiling point of thesolution.

The statements in the following multiple choices deal with the relationship between solute concentration and various colligative properties. Choose the statement which is true.a) Increasing the concentration of a nonvolatile solute in water decreases the osmotic pressure of the solution.b) Decreasing the concentration of a nonvolatile solute in water decreases the boiling point of the solution.c) Increasing the concentration of a nonvolatile solute in water decreases the boiling point of the solution.d) Decreasing the concentration of a nonvolatile solute in water decreases the vapor pressure of the solution.e) Decreasing the concentration of a nonvolatile solute in water decreases the freezing point of the solution.

The fact that boiling point of a pure solvent is lower than theboiling point of a solution of the same solvent is a directconsequence of the
