7PRACTICE PROBLEM
Consider the diagram below showing the vapor pressure curves for two solutions with equivalent concentrations. Solution A contains a nonvolatile solute while Solution B contains a volatile solute with a vapor pressure of around half of the vapor pressure of the pure solvent at a certain temperature.
Approximate the vapor-pressure curve for the pure solvent and determine its normal boiling point.
