Question

Nitrogen gas reacts with hydrogen gas to produce ammonia.
N2(g)+3H2(g)→2NH3(g)
How many grams of NH3 can be produced from 10.4 g of H2?
Express your answer with the appropriate units.

Answer 1

Solution:
ν(H₂)=10.4/2=5.2 mol
3 mol H₂→2 mol NH₃, so ν(NH₃)=(5.2/3)*2=3.47 mol
m(NH₃)=17*3.47-=58.99 g
Answer: 58.99 grams of NH₃.
