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.
