Henry's Law states that the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the liquid. The formula is C = kP, where C is the concentration of the gas, k is the Henry's Law constant, and P is the pressure. Given that 3.10 volumes of chlorine gas dissolve in 1 volume of water at 1 atm, the concentration C is 3.10 mol/L. Therefore, k = C/P = 3.10/1 = 3.10 mol/L·atm. However, the problem states that the correct answer is 0.13, which suggests a conversion or additional calculation not explicitly detailed here.
