    Hey, anyone who would be able to help me is an absolute hero. I have some questions on formulae and equations which I’m seriously stuck on. Here they are:

    Construct the formula of these hydrated salts, showing water of crystallisation.
    a) CoCl2O6H12
    b)Na2CO13H20
    c) AlN3O18H18

    Thanks

    For each consider the number of hydrogen present; this will give you a hint how many moles of water if crystallisation are present.
    Each mole will require one if the oxygens from the formula.
    Any oxygen not accounted for in the water must be part of the compound itself.
