    I was given a question in a lecture today:

    To the nearest order of magnitude, how many water molecules are required
    to form a layer on a coin that is one molecule thick?

    Can someone point me in the right direction or something?

    Thanks

    only one molecule is needed to form a layer one molecule thick ...

    however if you require the number of molecules required to make the entire layer you need the surface area of the coin in question.
