Use Henry's law to determine the molar solubility of helium at a pressure of 1.1 atm and 25 degree C. Henry's law constant for helium gas in water at 25 degree C is 3.70-10^-4 M/atm. You can treat Henry's law constant as an equilibrium constant. The goal of this problem is to find the concentration of helium dissolved in water that would be in equilibrium with the helium pressure over the water of 1.1 atm according to K = [He/P_He].

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...
