Physical chemistry Levine 6th exercise 9.54

air is 21% O2 and 78% N2 by mole fraction. Find the masses of O2 and N2 dissolved in 100.0 g of water at 20°C that is in equilibrium with air at 760 torr. For aqueous solutions at 20°C, K(O2 )= 2.95 × 107 torr and K

(N2 )= 5.75 × 107 torr.

    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...
