Thanks for the info. I'm still having trouble connecting the 1mg/l to the number of mg. in a kilo. One is weight, one is concentration. How do they connect? Is there some basic Science site you know of, that would have such a seemingly simple conversion? I haven't found such info yet. Thanks ahead of time.
You still didn't address the rest of my posts, validity etc.. but thanks for not trying to insult me. I appreciate it.
Also, Tom, you should know I never do any homework assigned by you. I'd rather keep my eye on the big picture: how does it work, does it work, who's Jim, how much money is being made by whom, etc...,
