At $298$ K$,$ the henrys law constant for oxygen is $0\mathrm{.}00130$ M$/$atm$.$ Air is $21\mathrm{.}0\%$ oxygen. at $298$ K$,$ what is the solubility of oxygen in water exposed to air at $1\mathrm{.}00$ atm? at $298$ K$,$ what is the solubility of oxygen in water exposed to air at $0\mathrm{.}899$ atm? If atmospheric pressure suddenly changes from $1\mathrm{.}00$ atm to $0\mathrm{.}899$ atm at $298$ K$,$ how much oxygen will be released from $3\mathrm{.}40$L of waterbin an unsealed container?
