Question 1

The solubility of CO in water at 0 °C and 1 atm CO pressure is 0.0354 mg of CO in 1 mL of water. Calculate the molarity of aqueous CO solution at 2 atm CO pressure.
◦ 1.58 × 10-3 M
◦ 6.32 × 10-2 M
◦ 1.59 M
◦ 2.53 × 10-3 M
◦ 3.16 × 10-3 M

Question 2

The vapor pressures of pure hexane and pure heptane at 25 °C are 151.4 mmHg and 45.62 mmHg respectively. A solution contains 0.800 mol fraction n-hexane and 0.200 mol fraction n-heptane. What is the composition of the vapor in equilibrium with this solution at 25 °C?
◦ 80.0% hexane, 20.0% heptane
◦ 50.0% hexane, 50.0% heptane
◦ 77.0% hexane, 23.0% heptane
◦ 45.0% hexane, 55.0% heptane
◦ 93.0% hexane, 7.0% heptane
