2NaHCO₃ → Na₂CO₃ + CO₂ + H₂O
Mole ratio NaHCO₃ : CO₂ = 2 : 1
No. of moles of CO₂ produced = (4.7 mol) × (1/2) = 2.35 mol
Molar volume of a gas at STP = 22.4 L/mol
Volume of CO₂ produced = (2.35 mol) × (22.4 L/mol) = 52.6 L
Mole ratio NaHCO₃ : CO₂ = 2 : 1
No. of moles of CO₂ produced = (4.7 mol) × (1/2) = 2.35 mol
Molar volume of a gas at STP = 22.4 L/mol
