Can you define more carefully what you mean by the chemical potential of
a solvent box? Can you point to such a calculation using some other
simulation package?
If the desired standard state is an ideal gas, then this is probably equivalent
to calculating the transfer free energy from gas to liquid of a single solvent
molecule. This can be done by "disappearing" one solvent molecule (in both
the gas and liquid phases). See section 5.6.18 of the Users' Manual.
On the other hand, if your standard state is the pure liquid (say at some
different temperature) that would require more work.
...good luck...dac
