Question

Calculate the solubility of oxygen in water at a partical pressure of 02 of 460 torrat 25 degree celsius

Answer 1

Do you have a graph that gives solubility at any other condition or do you have the Henry's law constant?

Answer 2

henrys lawconstant for oxygen in water is 1.28 X 10^-3 mol/(atm.L)

Answer 3

You know Henry's Law is written a bunch of ways. Since you gave k in mol/atm-L I think that means you are using
c = pk
c in mols/L = (640/760)*1.23E-3 = ?
