Answer
3 mol N2
Explanation
Given:
Moles of H2 = 9.0 mol
Equation: N2(g) + 3H2(g) → 2NH3(g).
What to find:
The moles of nitrogen gas required to completely convert 9.0 mol H2 gas to NH3 gas.
Solution:
From the Balanced equation of reaction given;
3 mol H2 completely reacts with 1 mol N2
∴ 9.0 mol H2 will require
[tex]\frac{9.0\text{ }mol\text{ }H_2}{3.0\text{ }mol\text{ }H_2}\times1\text{ }mol\text{ }N_2=3\text{ }mol\text{ }N_2[/tex]Hence, the moles of nitrogen gas required to completely convert 9.0 mol H2 gas to NH3 gas is 3 mol N2.
