    Does anyone have a compiled list of the formulas we need to know for calculations? e.g. mole formulas.

    mol = c x v
    mass = moles x molar mass
    PV=nRT (Volume is in m^3 remember!, n = moles and R = 8.314)
    Molecular formula = (Mr/Emperical formula) * Compound
    Relative atomic mass of an atom is the average mass of an atom of an element divided by mass of a carbon-12 atom then all multiplied by 12. Same for RMM.

    Edit: Eeek sorry it occurred to me on the way to college this morning that I said n was equal to the gas constant. I've fixed it now though, I don't think it would make a difference though since we're given the gas constant in the exams. My apologies though, I'm deeply embarrased but it was late and I was tired :P.
