You have 1.249 g of a mixture of NaHCO₃ and Na₂CO₃. You find that 12.0 mL of 1.50 M HCl is required to convert the sample completely to NaCl, H₂O, and CO₂.

What volume of CO₂ is evolved at 745 mm Hg and 25°C?

NaHCO3(aq) + HCl(aq) → NaCl(aq) + H₂O(l) + CO₂(g) Na₂CO3(aq) + 2 HCl(aq) → 2 NaCl(aq) + H₂O(l) + CO₂(g)
