Hey, NickNick, it'd help if you were careful with your typing when you're trying to show understanding. Regarding the water in your final formula -- it would never be 850 mg. If you weigh it, it would be 850 grams. If you measure by volume, it would be 850 ml.
Either way, based on what I understand from Trapper and Maniek, you probably won't end up with 1000 ml of solution. But you should have your 6.3 mg iodine+iodide per drop.
