The ‘mol’ mean 1 mol copies of the system. You should think of it as an energy density. In this case, it is the change in -TS for a single solute at infinite dilution, multiplied by Avogadro’s number.

-TS_H1 is the combined contribution from both water hydrogens. However, the contributions of the oxygen and hydrogen can’t really be separated, so the total value is what is most important.
Hope this helps,
