✔ 最佳答案
Molar mass of AgNO₃ = (107.9 + 14.0 + 16.0×3) g/mol = 169.9 g/mol
Molar mass of AgCl = (107.9 + 35.5) g/mol = 143.4 g/mol
2AgNO₃ + BaCl₂ → 2AgCl + Ba(NO₂)₂
Molar ratio AgNO₃ : AgCl = 2 : 2 = 1 : 1
No. of moles of AgNO₃ reacted = (16.4 g) / (169.9 g/mol) = 0.0965 mol
No. of moles of AgCl produced = 0.0965 mol
Mass of AgCl produced = (0.0965 mol) × (143.4 g/mol) = 13.8 g
