Questions & Step-by-Step Solutions

Which of the following is a correct application of Raoult's Law?
Correct Answer: Vapor pressure of a solution
  • Step 1: Understand that Raoult's Law relates to solutions and their vapor pressures.
  • Step 2: Identify the components of the solution (the solute and the solvent).
  • Step 3: Find the vapor pressure of the pure solvent (before adding the solute).
  • Step 4: Determine the mole fraction of the solvent in the solution.
  • Step 5: Use Raoult's Law formula: Vapor Pressure of Solution = (Mole Fraction of Solvent) x (Vapor Pressure of Pure Solvent).
  • Step 6: Calculate the vapor pressure of the solution using the values from the previous steps.
