Mole fraction (X) X = moles NaOH / total moles = moles NaOH / (moles NaOH + moles H2O) (2000 g water)/(18.0 g/mol) = 111.1 mol H2O. X = 20.0 moles / (20.0 moles + 111.1 moles) = 0.153 (no unit) Notice that the answer does not depend on the identity of the solute. The mole fraction of solute in any 10 m aqueous solution is 0.153! Mass % and ppm
