Helium & Argon Diffusivity: 10% He Lost, What % Ar?

[groovayness]

Helium has a molecular diffusivity three times greater than that for Argon. If a tank of water is charged with 0.5 atm of He and 0.5 atm of Ar and then allowed to stand in open contact wiht air, what percent of the Ar will have been lost when 10 percent of the He has been lost?
