Hi Hope!
In order to solve this problem, you would need to have the balanced chemical reaction.
A typical reaction involving nitrogen gas and hydrogen gas to form ammonia is the Haber process.
N2 + 3 H2 --> 2 NH3
Now that we have the balanced chemical equation, we can determine how many grams of ammonia formed from adding 16.0 g H2.
Using dimensional analysis to get moles of hydrogen,
(16.0 g H2) * ((1 mol H2) / (2.02 g H2)) = 7.92 mol H2
We can now, use the coefficients in the balanced chemical equation to get moles of NH3 produced.
(7.92 mol H2) * ((2 mol NH3) / (3 mol H2)) = 5.281 mol NH3 produced.
Lastly, we'll multiply the moles of ammonia produced by its molar mass to find the total grams of NH3 were formed.
5.281 mol NH3 * ((17.031 g NH3) / (1 mol NH3)) = 89.9 g NH3 formed
Hope this helps!
