Explanation:
Hello there!
In this case, since the reaction for the formation of ammonia is:

We can evidence the 1:2 mole ratio of nitrogen gas to ammonia; therefore, the appropriate stoichiometric setup for the calculation of the moles of the latter turns out to be:

And the result is:

Best regards!
MH₂ = 2×mH = 2×1g = 2 g/mol
The answer is D, because "Animals without a backbone are invertebrates."
