Question 1

Determine the vapour pressure of a solution at 28 °C that contains 62.5 g of fructose (C6H12O6) in 325.0 mL of water. The vapour pressure of pure water at 28 °C is 28.3 Torr.
◦ 16.9 Torr
◦ 36.9 Torr
◦ 24.9 Torr
◦ 27.8 Torr
◦ 28.8 Torr

Question 2

Calculate the volume of solution that has a vapour pressure of 31.27 mbar and contains 84.3 g of sucrose, C12H22O11, at a temperature of 25.0 °C. The vapour pressure of pure water at 25 °C is 31.7 mbar, the density of water is 1.00 g mL-1, and assume no change in volume occurs upon dissolution.
◦ 516 mL
◦ 31.8 mL
◦ 286 mL
◦ 204 mL
◦ 323 mL
