    Hi,

    I've been revising these Amount of Substance and most of the basic past exam questions i've done simply involve one topic such as 'work out the number of moles of x' or 'what is the mass of y' which worries me as if I was asked a more complex question I'm unsure of my ability to answer it.

    Therefore I was wondering if anyone would like to share the more difficult questions they've encountered relating to AS amount of substance.. i'm sure I'm not the only one who's in this situation!

    You could try just searching online or in your school folder for some chemistry worksheets/questions. That's how I practised the amount of substance bit (added with the vault of worksheets my teacher threw at me).
    For instance here are two sheets I did. They're both standard but it might get your brain rattling a bit.
    The pdf has the answers (but not the working out, it's the working out that's more important).
