How many moles of oxygen are in 7.4 moles of copper(II) permanganate?

The formula for copper(II) permanganate is $\textup{Cu}(\textup{MnO}_4)_2$. That means that for every molecule there are eight oxygen atoms. So there must be eight times as many moles of oxygen atoms as copper permanganate molecules.

Woops. I guess this forum doesn't like the "textup" command, so what I meant to say was

$Cu(MnO_4)_2$

I'm not sure what you are trying to do... maybe you're looking for \text?

$\text{Cu}(\text{MnO}_4)_2$

Yeah, that it. \textup is a legal Latex command (for upright text, as opposed to italics), but I guess it doesn't work here. Pretty much the same thing as \text. Thanks.
