There are 1.20*10^24 atoms of sodium in 2 moles of sodium.

Explanation:

One mole of a substance is defined by Avogadro as consisting of 6.022x10^23 atoms. This is Avogadro's number. To calculate the number of atoms in two moles of sodium, use dimensional analysis.

2.0 moles Na x (6.022*10^23g)/(1mol)=1.20*10^24 atoms of Na.
