While 14 g of baking soda (NaHCO3) is added to 550.0 mL of vinegar an aqueous solution of CH3COOH at 5% concentration by mass, the vinegar neutralizes the baking soda as well as converts it to CO2 gas, which bubbles out of the solution. Find out the limiting reagent in this reaction and compute the mass of CO2 produced.
