The partial pressure of O2 in air at sea level is 0.21 atm. Using the data in Table 13.

The partial pressure of O2 in air at sea level is 0.21 atm. Using the data in Table 13.2, together with Henry’s law, 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 597 torr.
