Explanation Given: Mass of glucose is 20 g . Mass of sucrose is 20 g . Mass of potassium acetate is 10 g . Volume of water is 100 mL . Explanation: Raoult’s law states that partial pressure of a substance is equal to the product of vapor pressure of the pure component and its mole fraction: P solution = χ solvent × P ∘ solvent where P solution is the vapor pressure of the solution, P ∘ solvent is the vapor pressure of pure component, and χ solvent is the mole fraction of the component. Here, the solvent is same for the three solutions, so the vapor pressure of the solution changes with the changing mole fraction of the solvent. Therefore, the vapor pressure of the solution is directly proportional to the mole fraction of solvent. P solution ∝ χ solvent Mole fraction of a solvent is equal to the number of moles of solvent divided by the total number of moles of solute and solvent. χ solvent = n solvent n solvent + n solute Moles of solvent remain same for all the solutions, but the moles of solute vary
