Determining The Percentage Of Water Of Crystallisation watch

    • Thread Starter

    How do you exactly determine the pecentage of water of crystallisation?

    An example of calculating the number of moles is in the CGP guide but I'm not too sure on how to do the first one (%)

    Also, how shall I represent the information in a table? So far I have:-
    - Intial mass
    - Final Mass
    - Mass Lost

    How will i represent data for the number of moles part?

    Your post is really confusing. Do you mean the number of waters of crystallisation i.e. whether it is a dihydrate, hexahydrate or dodekahydrate..?

    As for the table stuff, surely that depends on what experiment you are doing and what you need to calculate - for example if you are heating something that loses the waters of hydration you could have 4 columns - Compound, Mass, MW, Moles. Under compound you could have X.nH2O; X and H2O.
