text: Helium is the least water-soluble monatomic gas, and one of the least water-soluble of any gas (CF 4 , SF 6 , and C 4 F 8 have lower mole fraction solubilities: 0.3802, 0.4394, and 0.2372 x 2 /10−5, respectively, versus helium's 0.70797 x 2 /10−5), and helium's index of refraction is closer to unity than that of any other gas.
