At 298 K, the Henry\'s law constant for oxygen is 0.00130 M/atm.Air is 21.0% oxygen.


A) At 298 K, what is the solubility of oxygen in water exposed to airat 0.890 atm?


B) If atmospheric pressure suddenly changes from 1.00 atm to 0.890 atmat 298 K, how much oxygen will be released from 2.50 L of water inan unsealed container?

Heat and Mass Transfer. In a hydrogel based contact lens, oxygen diffusion from the air to the cornea occurs by first getting absorbed into the water of the hydrogel and the diffuse through this gelled matrix. Oxygen flux through one particular contact lens is 5micro L/cm2 * hr. If the outer surface of the contact lens is contact with atmospheric air and has a partial pressure of oxygen of 160mm Hg, what is the concentration of oxygen (in terms of partial pressure) on the inner surface of the contact lens that is in touch with the cornea? Assume that the oxygen is transported at a steady state. The diffusivity of oxygen through the contact lens is 3x10-9 m2 /s and the thickness of the lens is 10micrometers. The corneal surface and the lens are at 35oC. Assume that the properties of the contact lens are similar to the properties of water. Density of oxygen is 1.3 g/l.

Hint: to solve this problem you will need to determine to solubility of oxygen in the lens (assumed to have the properties of water). The effect of temperature and pressure on the Henry’s constant for a number of gases can be determined as described below: https://chemengineering.wikispaces.com/Henry%27s+Law
