Lets take Ca(2+), then 500 mmol/2/liter = 250 mmol/liter, then convert
it into centimoles (cm) by the fact that 1 centimole = 10 millimole.
In fact mmol/Z is equivalent to milliequivalents.

The next problem that immediately confronts is that ion-exchangers are
solids. Meauring volumes of ion exchangers is not a useful idea. Are
you sure that the required conversion is mmol per Z per liter of ion
exchanger to centimoles/kg of ion exchanger?
