...ah-h-h, but atomic-level molecules are sneaky...the little ones sneak "in & out" faster than the big ones:
AIR = 100.00%.....28.966 MW
_N2 = 78.084%.....28.013 MW
_O2 = 20.946%.....31.999 MW
_Ar = _0.934%.....39.948 MW
H20 = _0.400%.....18.020 MW (water vapor)
_He = _0.000524%.._4.000 MW
_H2 = _0.000055%.._2.020 MW

Reason: added Helium (He) and Hydrogen (H2)
