2AgNO₃ + BaCl₂ → 2AgCl + Ba(NO₃)₂
Mole ratio AgNO₃ : AgCl = 2 : 2 = 1 : 1
Molar mass of AgNO₃ = 107.9 + 14 + 16×3 = 169.9 g/mol
Molar mass of AgCl = 107.9 + 35.5 = 143.4 g/mol
Number of moles of AgNO₃ = 5.0/169.9 mol
Number of moles of AgCl made = 5.0/169.9 mol
Mass of AgCl made = (5.0/169.9) × 143.4 = 4.2 g
Mole ratio AgNO₃ : AgCl = 2 : 2 = 1 : 1
Molar mass of AgNO₃ = 107.9 + 14 + 16×3 = 169.9 g/mol
Molar mass of AgCl = 107.9 + 35.5 = 143.4 g/mol
Number of moles of AgNO₃ = 5.0/169.9 mol
Number of moles of AgCl made = 5.0/169.9 mol
Mass of AgCl made = (5.0/169.9) × 143.4 = 4.2 g
