Questions & Step-by-Step Solutions

What is the vapor pressure of a solution containing 2 moles of solute and 3 moles of solvent, assuming ideal behavior? (2022)
  • Step 1: Identify the number of moles of solute and solvent. Here, we have 2 moles of solute and 3 moles of solvent.
  • Step 2: Calculate the total number of moles in the solution. Total moles = moles of solute + moles of solvent = 2 + 3 = 5 moles.
  • Step 3: Calculate the mole fraction of the solvent. Mole fraction of solvent = moles of solvent / total moles = 3 / 5.
  • Step 4: Use the formula for vapor pressure of the solution. Vapor pressure of solution = (moles of solvent / total moles) * P0.
  • Step 5: Substitute the values into the formula. Vapor pressure of solution = (3 / 5) * P0.
  • Step 6: Simplify the fraction. 3 / 5 = 0.6.
  • Step 7: Write the final answer. Vapor pressure of solution = 0.6 P0.
