Answer: The answer is 5 atoms.

Explanation: It must be nitrogen atom (N) which has 20% by mass and not N2

Therefore, assuming it as Nitrogen atom

Molecular weight = 350g.

Weight of Nitrogen atom = (350 * 20) / 100 = 70g.

Therefore, the number of Nitrogen atoms = Total mass of Nitrogen / Atomic  mass of Nitrogen = 70 / 14 = 5 atoms.
