Dear Jonathan, I think that "mass fraction of X in air" is equivalent to "mass mixing ratio of X in air", "mixing ratio" alone would rather equivalent to volume or mole mixing ratio.
If water vapor is a special case in that the humidity mixing ratio excludes X=water from the denominator, whereas all the other mixing ratios include X, I think we need to add this to the explanations. And with this we could conclude the affair?
