`structure.solvent.get_ion_counts(simlify_config, charge_net, n_waters, water_molecule_volume=28.78277638661025)` ¶

Compute the number of cations and anions to achieve desired ionic strength.

PARAMETER	DESCRIPTION
`simlify_config`	A simulation context for system preparation. TYPE: `SimlifyConfig`
`charge_net`	Total system charge. Will add counter ions if `charge_neutralize` is `True` in `simlify_config`. TYPE: `int \| float`
`n_waters`	Total number of water molecules in the system. TYPE: `int`
`water_molecule_volume`	Approximate volume of a water molecule in Å³. TYPE: `float` DEFAULT: `28.78277638661025`

RETURNS	DESCRIPTION
`dict[str, int]`	Cations and anions that needs to be added to the system. For example, `2` would
`dict[str, int]`	mean two cations need to be added, but `-2` would mean two anions.
