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.
