Look at the units. If you forget during the MCAT, carrying the units through your calculations will often answer half the question.

Now stop studying and go and have some fun.

It's the changing condition of the typical pre-med as the MCAT approaches. ;)

Good one UCLA.

Quick question though: when do you multiply by the coefficients, and when do you not when dealing with all those Enthalpies, Entropies, Energies, etc. ???

I think enthalpy of entities in their elemental state is 0 J for enthalpy of formation. But as far as there are moles you just have to multiply by the coefficients.
 
Basically, you multiply by the mole coefficients for everything but reduction potentials in electrochemical cells.

ah, yeah, that's it. got it! thanks!
