Balanced chemical equation is
Number of moles of nitrogen = \(50\ g\times \frac{1\ mol}{28\ g} = 1.786\ mol\)
Number of moles of hydrogen \( = 8\ g\ \times \ \frac{1\ mol}{2\ g} =4\ mol\)
According to equation,
Number of moles of H2 reacts with 1.786 mol N2
= 3/1 × 1.786 = 5.358 moles
But moles present in H2 = 4
So complete H2(g) will take part in reaction. So, H2 iş limiting reagent.
Amount of NH3 (g) formed by 3 mol of H2 = 2 mol
Ammonia formed by 4 mol of H2 = \(\frac{2}{3}\times 4\ mol\)
= 2.66 mol
2.66 mol = 2.66 × 17 = 45.22 g
