Which of the following statements is TRUE for this system at equilibrium condition? Select one: a. The gas phase just above the liquid solution is composed of pure ethanol. O b. No gases of H20 or ethanol is present above the liquid solution at 25 "C since their boiling points are way above this temperature. Oc. The gas phase just above the liquids solution has a higher mole fraction of gaseous ethanol than water vapor. O d. The gas phase just above the liquid solution is composed of pure H20.

What is the concentration of O2 in freshwater? Air temperature= 295.65 K. Air pressure = 1 bar(about = to 1atm). Henry's constant, from the table= 1.3 x 10-3 mol/ (kg x bar). PO2 can be calculated from the fact that oxygen is .21 mole fraction of air. Hint- The partial pressure of a gas in a mix of gasses is found by multiplying the total pressure by the mole fraction of that gas. Find the concentration in g/kg from the answer you just got.
From your data in Part 1 of the experiment, you calculate the natural log of the partial pressure of water and 1/T value in K for 5 points between 50°C and 80°C. You make a graph of In(P) vs. 1/T and determine that the slope of the linear line is -4800 K. Use this information to calculate AHvap of water. Make sure to use R = 8.314 J mol-1-K-1.
