We’re being asked to determine the solubility of He in water.
Recall that the solubility of a gas is given by Henry’s law:
where Sgas = solubility of the gas (in mol/L or M), kH = Henry’s law constant for the gas, Pgas = partial pressure of the gas.
The Henrys law constant for helium gas in water at 30 oC is 3.7 10 - 4 M/atm; the constant for N2 at 30 oC is 6.0 10 - 4 M/atm.
If helium gas is present at 1.7 atm pressure, calculate the solubility of this gas.
