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.
