Answer» The equations given below relate to the manufacture of sodium carbonate (Molecular weight of Na₂CO₃ = 106). NaCl + NH₃ + CO₂ + H₂O $\overset{}{\to}$ NaHCO₃ + NH₄Cl 2NaHCO₃ $\overset{}{\to}$ Na₂CO₃ + H₂O + CO₂ Questions (a) and (b) are based on the production of 21.2 g of sodium carbonate. (a) What mass of sodium hydrogen carbonate must be heated to give 21.2 g of sodium carbonate (Molecular weight of NaHCO₃ = 84)? (b) To produce the mass of sodium hydrogen carbonate, calculate what volume of carbon dioxide, measured at STP would be required?
