First, lets examine the formula for that of Ammonia.
Ammonia = NH3
Notice that in the formula, there are 3 hydrogen atoms in a single ammonia molecule. This being said, if there are 200 molecules of ammonia in the given scenario, multiply 200 by 3.
× ← Amount of (H) Atoms Present in 200 (NH3) Molecules
Hope this helps!
Despite being an extremely rare gas on Earth, hydrogen is the most common element in the universe. This is due to the fact that hydrogen is the fuel for stars, as it undergoes the fusion nuclear reaction to form helium and release the energy to sustain the star. Therefore, the answer to this question is hydrogen.
