Formulas in Chem? (1 Viewer)

[Fortify]

I've already for a few formulas, wondering if I'm missing any? So far I got:

n = N / N(avo)
molarity = n / vol
n = m / MM
c = n / Vol
c1v1 = c2v2
[DELTA]H = -mc[DELTA]T

yeah that's pretty much it.

Ummm...

n = V / MV (molar volume)

And remember that (delta)H measures energy per mole, so divide whatever you get for -mc(delta)T by the number of moles used in the reaction.

What's molar volume? =S

Volume of 1 mole of gas.

0*C 100KPA = 22.71L/mol
25*C 100KPA = 24.79L/mol

Thanks tommykins =] sorry I didn't reply sooner

I think it's covered more in Year 12, don't really worry about it at the moment.
