Hi Balaji,


It is possible to specify the exact number of ions you want on
the addions line so you just need to work out how many of each type of counter
you need for the concentration you want. You know how many water molecules you
have so this shouldn't be too difficult.


Then just do say:


addions mymol Cl- 20

addions mymol Na+ 20


to get 20 x NaCl


Good luck,

for example ...

magnesium chloride , cobalt chloride etc in the way how they

use it for crystallization ..
