I made a program like this while in chemistry. It didn't go parentheses however (bravo). But it did go on to use the molar mas to do stoichiometric calculations (I should upload it).

now, let's say I wanted the molar mass of 2H2O. Would it handle it?

I think so, but I have to input it as (H2O)2, so the program parses it correctly.

@c_plus_plus: I'd really appreciate that, as I was pondering making that, but if you've got a working version, that'd be just great. What capabilities does it have?
