How many neon atoms are there in five moles?

  • chemistry -

    Ok. I'll do my best to help you out.
    1 mole of Neon = 20.1797 g Ne.
    In this case there are 5 moles of Ne.
    We also know that there are
    6.022x10^23 atoms of Ne per mole of Neon by definiton of Avogrado's Number and moles.

    So we set up something like this:
    20.1797 g Ne/1 mol Ne
    *5 mol Ne *6.022*10^23 Ne atoms/1 mol Ne

    This was kinda hard to type out but this should be right. Hope this helps. Peace.
