The partial pressure of O2 in air at sea level is 0.21 atm. The solubility of O2 in water at 20 ∘C , at 1 atm gas pressure, is 1.38×10−3 M. Using Henry's law and the data in the introduction, calculate the molar concentration of O2 in the surface water of a mountain lake saturated with air at 20 ∘C and an atmospheric pressure of 660 torr .

The partial pressure of oxygen gas in our atmosphere is 0.21 atm. This is the partial pressure at which human lungs have evolved to be able to breathe this gas. A SCUBA diver, will thus still have to breath oxygen at this pressure even when diving way down in the water. If a mixture of helium and oxygen (heliox) in his tank is at a pressure of 7.00 atm, what must the partial pressure be of helium to keep the...

Henry’s law states that the solubility of a gas is directly proportional to the partial pressure of the gas if the temperature is constant. Hyperbaric chambers, which provide high pressures (up to 6 atm) of either air or pure oxygen, are used to treat a variety of conditions, ranging from decompression sickness in deep-sea divers to carbon monoxide poisoning. Look up the Henry’s Law Constant (kH) for N2, O2, and CO2 in the textbook. a) Calculate the solubility (concentration in...

Henry's Law states that the quantity of a gas that will dissolve in a liquid is proportional to the partial pressure of the gas and its solubility coefficient (its physical or chemical attraction for water), at a given temperature. Henry's Law: The volume of a gas (Vx) dissolved in a liter of water is Vx = (pX)*(SC), where pX is the partial pressure in atmospheres and SC is the solubility coefficient. a) At 1 atm and 37 degrees Celsius, the...
