1 molecule of NO2 included N atom and 2 oxygen atoms, so a total of 3 atoms per molecule.
1.3 x 10^22 times 3 = 3.9 x 10^22 atoms
The total number of atoms in 1.3 x 10^22 molecules of N(O)2 is 3.9 x 10^22 atoms since each molecule of N(O)2 consists of three atoms. ;
In 1.3 × 1 0 22 molecules of NO 2 , there are 3.9 × 1 0 22 atoms. Each molecule has three atoms (1 nitrogen and 2 oxygen). This calculation is done by multiplying the number of molecules by the number of atoms per molecule.
