Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A solution of glucose has a mass percentage of 5%. Calculate the vapor pressure decrease when 10 g of glucose is added to 100 g of water with a vapor pressure of 23.8 mm Hg.

💡 Hint: Start with the definitions and work through molar conversion.

Challenge 2 Hard

If the vapor pressure of acetone is 80 mm Hg and that of chloroform is 150 mm Hg, what is the expected vapor pressure of a solution made by mixing equal moles of both?

💡 Hint: Think about how to balance the contributions of both solvents.
