✔ 最佳答案
Molar mass of Cl₂ = 35.5 × 2 g/mol = 71.0 g/molMolar mass of HCl = (1.0 + 35.5) g/mol = 36.5 g/mol
H₂ + Cl₂ → 2HCl
OR: Mole ratio H₂ : Cl₂ : HCl = 1 : 1 : 2
Molar mass of Cl₂ = 35.5 × 2 g/mol = 71.0 g/mol
No. of moles of Cl₂ used = 0.0251 mol
No. of moles of H₂ used = 0.0251 mol
No. of moles of HCl produced = (0.0251 mol) × 2 = 0.0502 mol
Molar mass of HCl = (1.0 + 35.5) g/mol = 36.5 g/mol
Mass of HCl produced = (0.0502 mol) × (36.5 g/mol) = 1.83 g

It is given that hydrogen is in excess
Then how it can ask to find moles of hydrogen used?
