Please Calculate the solubility of oxygen in water at the top of Mt. Everest where the atmospheric pressure is 0.340 atm. The mole fraction of O2 in air is 0.209. Assume the kH of O2 is 1.30 × 10-3 mol/(L • atm).
The density of the hydrogen peroxide solution is 1.01 g/ml and the solution contains 3.40% H2O2 by mass. The vapor pressure of water at 24 celsius is 22mmHg. Based on this data and information calculate the molar volume at STP.
