✔ 最佳答案
0.28 moles H2
0.187 moles NH3
N₂(g) + 3H₂(g) → 2NH₃(g)
Mole ratio N₂ : H₂ : NH₃ = 1 : 3 : 2
Molar mass of N₂ = 14.01 × 2 = 28.01 g/mol
No. of moles of N2 = (0.0935 g)/(28.01 g/mol) = 0.0935/28.01 mol
No. of moles of H2 required = (0.0935/28.01 mol) × 3 = 0.0100 mol ..... (Ans)
No. of moles of NH₃ formed = (0.0935/28.01 mol) × 2 = 0.00676 mol ..... (Ans)
