At $25$oC$,$ the solubility of oxygen in water is $2\mathrm{.}86$ x $104$ M when the partial pressure of the oxygen above the water is $0\mathrm{.}210$ atm. Determine the Henry$$s law constant for oxygen at $25$oC and also the solubility of oxygen when its partial pressure above the water is $3\mathrm{.}10$ atm.
