KMnO4
Do you mean how many atoms in that many moles? Will assume so unless otherwise told.
2.55 moles KMnO4 (6.022 X 10^23/1 mole KMnO4)
= 1.54 X 10^24 atoms of potassium permanganate
now that I think about it you might have meant grams per mole
2.55 moles KMnO4 (158.04 grams/1 mole KMnO4)
= 403 grams of potassium permanganate
I can't think of any other variant on your question.
