There are 6xx6.022xx10^23 atoms in 2.00*mol NO_2(g).

Explanation:

In the one mole of NO_2, there are "Avogadro's number" of NO_2 molecules; i.e. N_A NO_2 molecules.

And thus in 2.00*mol of NO_2 there are 6xxN_A nitrogen and oxygen atoms. In terms of N_A, how many oxygen atoms, and how many nitrogen atoms in this quantity?
