    Hi,

    I'm having some trouble finishing this problem off.

    I've used the ideal gas equation to find V/n = 0.0247 m^3 per mol. However, I'm confused as to how to get m^3 per atom/molecule correctly from this.

    I thought you multiplied by the Avagadro's number but you divide through by it.

    Please could someone explain why this is, thanks

    0.0247m^3 per mole

    is the same as saying

    0.0247m^3 per 6.02x10^23 atoms/molecules

    so if that many molecules occupy 0.0247m^3, then one molecule must occupy 1/6.02x10^23 of that.

    just think, if you multiply though my avagadros number you're basically saying 1 molecule occupies 6.02x10^23 time the volume of an entire mole of molecules, and that makes no sense!
