    anyone know the molecular mass for graphene?
    There is no mr for graphene since it is like a carbon polymer, I think this makes me come to think that it should
    be about carbon and the surface area of the earth

    Just got silver, I found it useful to first find out the two middle ones (i.e. the ones that must have 6 not within 50 years).

    Do you want a bigger hint?
    I've done silver, thanks. It's Gold that I need to do now. Thanks anyway, though. I was just joking. :hug:

    Search for the mass per m2 for graphene. It's easy to find if you google. That should be a bit of a starting point

    have you done it? I already have the mass per m2 but I'm not sure what to do with it. I tried dividing the SA of the earth with it. Wrong answer

    There's a lot of information out there about isomers. I googled and found a page of notes on isomers of octahedral complexes which told me how many isomers there would be for an octahedral complex with 6 different ligands. I then worked out the phosphorus compound from that as well.

    You can sit and try and draw out all the isomers, but I can tell you that you'll be there for a while...!

    I have indeed. If you have the mass per m2 of graphene, and the surface area of the Earth in m2 then it is a very simple calculation...

    It's one of those ones that sort of stares you in the face, but sometimes you can't see for looking!

    I don't have molymods at home so I am resorting to rolling up pieces of paper, colouring them different colours, blu-tacking them together and seeing how many different stereoisomers I can get until I get bored... Please someone save me from this insanity! Can someone teach me a more scientific method of doing this?
