Challenge Problems

Push your limits with challenges.

Question 1

You have a solution with a vapor pressure of 50 mmHg at 25°C containing 10 g of non-volatile solute in 200 g of solvent. Calculate the vapor pressure of pure solvent.

💡 Hint: Calculate the mole fraction first.

Question 2

A solution is prepared by mixing two volatile liquids, A and B. If the mole fractions are 0.6 for A and 0.4 for B, and their pure vapor pressures are 80 mmHg and 60 mmHg, calculate the total vapor pressure of the solution.

💡 Hint: Remember to use the mole fractions to find the partial pressure contributions.
