At 298 K, the Henry's law constant for oxygen is 0.00128 M/bar. Air is 21.0% oxygen. At 298 K, what is the solubility of oxygen in water exposed to air at 1.00 bar? Number At 298 K, what is the solubility of oxygen in water exposed to air at 0.893 bar? Number If atmospheric pressure suddenly changes from 1.00 bar to 0.893 bar at 298 K, how much oxygen will be released from 5.50 L of water in an unsealed container? mol 0 Previous Give Up & View
