Rainbow Lake is at an elevation where the air pressure is 670 torr, and the current water temperature is 20°C. A particular fish species requires a minimum dissolved oxygen concentration of about 8.5 mg/L in order to live.
Note: The Henry's Law constant for O2 at 20°C is 1.38x10-3 M/atm.
Question 6:
What is the dissolved oxygen concentration, in mg/L, under the existing conditions at Rainbow Lake?
