Recall that the solubility of a gas is given by Henry’s law:
where Sgas = solubility of the gas (in mol/L or M), kH = Henry’s law constant for the gas, Pgas = partial pressure of the gas.
Determine the solubility of oxygen in water at 25oC exposed to air at 1.0 atm. Assume a partial pressure for oxygen of 0.21 atm . (kH,O2 = 1.310-3M/atm.)
