The partial pressure of O2 in air at sea level is 0.21 atm. The solubility of O2 is 1.38E-3 at 1 atm.
The partial pressure of O2 in air at sea level is 0.21 atm. The solubility of O2 is 1.38E-3 at 1 atm. Use Henry's law to calculate the molar concentration of O2 in the surface water of a mountain lake saturated with air at 20°C and an atmospheric pressure of 622 torr.
