At 298 K, the Henry's law constant for oxygen is 0.00130 M/atm. Air is 21.0% oxygen. At 298 K, what is the solubility of oxygen in water exposed to air at 1.00 atm? solubility: M At 298 K, what is the solubility of oxygen in water exposed to air at 0.894 atm? solubility: M If atmospheric pressure suddenly changes from 1.00 atm to 0.894 atm at 298 K, how much oxygen will be released from 3.60 L of water in an unsealed container? amount: mol
