A solution is prepared by dissolving 11.60 g of a mixture of sodium carbonate and sodium bicarbonate in 1.00 L of water. A 300.0-cm3 sample of the solution is then treated with excess HNO3 and boiled to remove all the dissolved gas. A total of 0.941 L of dry CO2 is collected at 298 KK and 0.972 atm. Find the molarity of the carbonate in the solution and the bicarbonate in the solution.
Sodium bicarbonate reacts with hydrochloric acid in a gas-forming reaction to produce aqueous sodium chloride, water, and carbon dioxide gas: NaHCO3(s) + HCl(aq) → NaCl(aq) + H2O(l) + CO2(g) Determine the mass of CO2 gas produced when 8.67 g of NaHCO3 is added to a solution that contains 5.65 g of HCl. ___g?
