yes i do have the mole chapter, i don't really study for it, i don't really know the formulas, but i always use my knowledge in physics in calculating moles. i always see the units of whatever i want to find, and i got what i want just buy looking at the unit. the units always giveaway the formula. for example, mol/dm3 = concentration, which is simply number of moles divided by the volume. for some reason, this method always works for me then some memorisation of formulas.
Hmmm... making equations... what do you mean by that, care to explain it to me? i bet i know it, its just that... i need an example of a question :D
i also have classes from 8 to 4, you're not alone!
