Question 1

Given that the vapor pressure of pure n-hexane and pure n-heptane at 25 °C are 151.4 mmHg and 45.62 mmHg respectively, calculate the total vapor pressure above a solution containing only n-hexane and n-heptane in which the mole fraction of n-hexane is 0.600.
◦ 87.9 mmHg
◦ 197 mmHg
◦ 106 mmHg
◦ 109 mmHg
◦ 170 mmHg

Question 2

Henry's Law constants for aqueous solutions at 25 °C are 8.20 × 10-7m/mmHg for N2 and 1.62 × 10-6m/mmHg for O2. Determine the solubility of nitrogen in water under an atmospheric pressure of 760 mmHg, assuming that air is 80% N2 and 20% O2.
◦ 6.23 × 10-4m
◦ 7.79 × 10-4m
◦ 4.99 × 10-4m
◦ 1.25 × 10-4m
◦ 6.16 × 10-3m
