    Each picture corresponds to an element. You might want to try running some of the images through Google's reverse image search.

    Find the material(s) that the mass is made of, then work out the number of moles of each and total number of atoms. Hope this helps

    Not to cause offence or anything but please do refrain from putting the answers up (yeah, spoiler tagging it counts as well)- leading people through the answers would be much more useful.

    Still stuck on Rg...I think I have the right idea but none of my answer combinations are working.

    EDIT: Done it. I really owe a debt to SpinyGecko who kindly answered all of the PMs I sent to him/her (I hope it doesn't count as spam! )

    Hints (hopefully they don't reveal too much):

    Historically a lot of measurements such as the kilogram are "pegged" to a real life artefact. This is true of the kilogram.
