I want to know if there is a way to find number of solvent molecules that are directly embracing a solute molecule (something like a reference or table that shows waters of hydration).

Particularly I am interested in solvents such as water or ethanol, and the solutes acetone, acetaldehyde, 1-butanol, methylene blue, benzene, anthracene, and phenanthrene.

    $\begingroup$ This is too broad. For a single atom ion this would sort of be answerable. But there are large molecules like proteins or polymers where the solute molecule could contact hundreds (or more) of solvent molecules. $\endgroup$ – MaxW May 6 '16 at 5:18
