Question

hydrogen reacts with nitrogen to produce ammonia .determine how much amonia would be produced if 200 g of hydrogenreacts with excess of nitrogen

Answer 1

The balanced chemical equation is:
N₂ + 3H₂ $\to$2 NH₃
Molar mass of H₂ = 2 g/mol
​Molar mass of NH₃ = 17 g/mol
​According to balanced chemical equation;
6 g/mol of H₂​(3 $\times$ 2g/mol) produces 34 g/mol NH₃​(2$\times$17g/mol)
Mass of ammonia produced by 200 g of H₂ =$\frac{34}{6}\times 200$ = 1133.33 g ammonia will be formed.
