Dryness Fraction question
With the use of Ammonia (R717) properties table, find the enthalpy of the refrigerant if the saturation temperature is -10C and the dryness fraction, x, is 0.9.
can anyone help me with this? i do not understand the use of dryness fraction

Check one's text, but if 'dryness' is like steam quality, then it refers to the fraction of a saturated two phase system which is gas (vapor), as opposed to the other fraction which is liquid.
I assume dryness does not refer to the water content, which would lead to ammonium hydroxide, or 'aqua' ammonia.
