    Carbon atoms .....

    No carbon atom has a mass of 12.011 amu. 12.011 g/mol is the weighted average of the naturally occurring isotopes of carbon.

    Clearly, if you had 12.011g of a natural assortment of carbon atoms, then you would have "exactly" one mole of carbon atoms, or 6.022x10^23 carbon atoms.

    It is based on the "definition" of a mole:

    1 mol C atoms = 6.022x10^23 C atoms

    1 mol C atoms = 12.011 g C atoms

    Molar mass of naturally ocurring Carbon is 12.011 g/mol

    so you have exactly 1 mole of C in your nass.

    number of atoms in a mole of an element is avogadros number of atoms or

    6.02 * 10 ^23 atoms
