Keep in mind Nitrogen gas is a diatomic element please.
And 1 mole of nitrogen contains 2 atoms
Remember, a molecule is a particle with multiple atoms, alright??
The option is B please
1 mol N₂ ----> 6.02 x 10²³ molecules N₂
0.2 mol N₂ ---> 0.2 x 10²³ molecules N₂
= 1.204 x 10²³ molecules N₂
= 1.204 x 10²³ x 1 molecule N₂
= 1.204 x 10²³ x 2 atoms N
= 2.41 x 10²³ atoms of N
