how many atoms of carbon have the exact mass of 12.011g/mol, explain?

1 carbon is 12 or 14

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
