Approximately #6.02*10^23# atoms.

Explanation:

A mole of a substance is defined as having around #6.02*10^23# units of that substance. This number is called Avogadro's number, and is denoted by #N_A#. So, we can say that #N_A~~6.02*10^23 \ "mol"^-1#. Therefore, a mole of atoms is #6.02*10^23# atoms.

When you see the atomic mass of the elements on the periodic table, a single mole of them will have the same atomic mass as denoted, but in grams instead of atomic mass units.
