12. A 6.35 gram sample of a mixture containing sodium carbonate is found to react completely with 75.0 mL of 1.25 M hydrochloric acid. The other components of the mixture did not react. The products of the reaction between the sodium carbonate and hydrochloric acid were sodium chloride, carbon dioxide, and water. (a) What was the percent by mass of sodium carbonate in the original mixture? (b) How many liters of carbon dioxide would have been generated if it had been collected at STP?
