Question 1

Oxygen gas makes up 21 % of the atmosphere by volume. What is the solubility of O2(g) in water at 25°C if the atmospheric pressure is 741 mmHg?  The Henry's law constant for oxygen gas at 25°C is 1.3 × 10–3 mol/L·atm.
◦ 2.7 × 10–4 M
◦ 1.3 × 10–3 M
◦ 6.2 × 10–3 M
◦ 9.6 × 10–3 M
◦ 0.96 M

Question 2

Pure benzene, C6H6, freezes at 5.5° and boils at 80.1°C.  What is the boiling point of a solution consisting of cyclohexane (C6H12) dissolved in benzene if the freezing point of this solution is 0.0°C? (For benzene, Kf = 5.12 °C/m, Kb = 2.53 °C/m; for cyclohexane, Kf = 20.0 °C/m, Kb = 2.79°C/m)
◦ 77.4°C
◦ 80.9°C
◦ 82.8°C
◦ 83.1°C
◦ 91.2°C
