Typing CO_2 easily
I'm writing my dissertation and that involves typing a lot of $mathrm{CO_2}$. I'd like to make a macro for it that's a lot easier to type, but if I put newcommand{co2}{mathrm{CO_2}}, for example, it gives me the error that mathrm can only be used in math mode. But using newcommand{co2}{$mathrm{CO_2}$} doesn't work either.
Is there a way for me to make a macro that makes typing CO_2 easier, even if it doesn't use mathrm?

For anyone new to latex reading this question: There are two separate issues here. One is that mathrm can only be used in math mode. The second one is that you can't (usually) have digits in macro names.

I'm not sure if this is a question about how to use co2 as a macro name or just a question about how to subscript in text mode. If you use coo, the macro
newcommand{coo}{ensuremath{mathrm{CO_2}}}
works fine in both text and math mode. If you're only planning to use the macro in text mode, COtextsubscript{2} works.
documentclass{article}
newcommand{coo}{ensuremath{mathrm{CO_2}}}
newcommand{cooo}{COtextsubscript{2}}
begin{document}
With ensuremath: Text coo and math $coo$ both look fine.
With textsubscript: Text cooo is fine, but math $cooo$ isn't.
end{document}
Don't forget the trainling and space after the call in text mode.

Especially when using macros, I think that using xspace is really convenient. You put anxspaceat the end of your macro and it will decide if a space is necessary or not.

(Note also that, as mentioned in John Kormylo's answer, there is also a package chemformula. It seems to be very similar, and allows you to do the same things in very similar ways. It is a more recent package, but I have no experience with it.)
