    I read somewhere that it can be written as dm3 or dm-3 how are these the same thing? Also for concentration like mol L-1 why does it have the -1 written after it thank you.

    mol/dm3 = mol dm-3

    Instead of dividing moles by dm3, you are multiplying moles by 1/dm3 (dm-3), which is the same thing.

    is this in rates?

    often while calculating the rate constants, the -3 gets inverted, but usually concentration is written as mol dm^{-3}   or    mol/dm^{3}

    the -1 just means that there is this many of this per mole, like x many grams per mole
