with all due respect it is people like u that discourage knowledge thirsty people,since its simple why dont you help,lets be good to one another.op i am not a chemistry person i would have helped.

Psylas,u call it simple and ask me if I am not ashamed, yet nothing from u,not even how to convert to moles.
Well, I see no reason why you should be so condescending,this is science not religion, I don't think I have sinned by not being able to solve the "simple thing".
If this was posted to yahoo answers,the only insult i'd get would be the answer, Uncivilised Nigerians like you are the reason we are still so behind
