How many moles of Oxygen are contained in 2.50 mol of KMnO4???
Molecular weight of KMnO4=158.034 g/mol
2.50 X 158.034=395.085
Since molecular weight of Oxygen=15.9994g/mol, therefore,
395.085/15.9994=24.694 moles of Oxygen.
P.S. You have to check this for accuracy!!!. We are NOT chemists, but Math nuts!!!!.

+1038 Are you related to Sorasyn? You’re not deadly enough to be him, but you have a comparable lack of chemistry skills. You also have CDD. Of course many on here do, so it’s not really definitive, it’s just a “birds of a feather” kind of relation.
You are right about the not a chemist part . . . and the nut part, too.

Nauseated, since you are such a 'genius' [interprete as 'know-it-all' ] why don't you just answer the question!!
Perhaps this would present a problem for you ?
+1038 . . . It’s not that it would present a problem generally . . . it’s the “C” in CDD. I was exposed to contagious dumbness. I needed to wait for it to wear off a little before I risked giving an answer. If I gave a wrong answer, someone (you) might troll me and that looks bad on my permanganate (permanent) record. Thanks for the generous compliment. I’ve never given a wrong answer -- even in the most adverse of conditions, so the risk is minimal I’m sure.
Here’s the answer:
2.50 moles of potassium permanganate (KMnO4) contains (2.50*4 =) 10 moles of oxygen.

ok, I will take your word for it Nauseated. Since it is not my question I have nothing to lose :))
I'll let you into the hall of credit fame tonight. Pat.pat. pat, There is a good dog :)
