Questions & Step-by-Step Solutions

If the vapor pressure of pure solvent A is 100 mmHg, and the mole fraction of A in the solution is 0.6, what is the vapor pressure of the solution according to Raoult's Law?
  • Step 1: Identify the vapor pressure of pure solvent A, which is given as 100 mmHg.
  • Step 2: Identify the mole fraction of solvent A in the solution, which is given as 0.6.
  • Step 3: Recall Raoult's Law, which states that the vapor pressure of the solution (P_solution) is equal to the mole fraction of the solvent (X_A) multiplied by the vapor pressure of the pure solvent (P_A^0).
  • Step 4: Substitute the values into the formula: P_solution = X_A * P_A^0.
  • Step 5: Calculate the vapor pressure of the solution: P_solution = 0.6 * 100 mmHg.
  • Step 6: Perform the multiplication: 0.6 * 100 = 60 mmHg.
  • Step 7: Conclude that the vapor pressure of the solution is 60 mmHg.
