Answer :
Answer:
[tex]3\text{ moles of a}mmonia[/tex]Explanation:
Here, we want to get the number of moles of ammonia produced
From the balanced equation of reaction:
3 moles of hydrogen gas produced 2 moles of ammonia
4.5 moles of hydrogen gas will produce x moles of ammonia
Mathematically:
[tex]\begin{gathered} 3\times x\text{ = 4.5}\times2 \\ x\text{ = }\frac{4.5\times2}{3} \\ x\text{ = 3 moles} \end{gathered}[/tex]
