A 2.36-gram sample of NaHCO3 was completely decomposed in an experiment. 2NaHCO3 → Na2CO3 + H2CO3 In this experiment, carbon dioxide and water vapors combine to form H2CO3. After decomposition, the Na2CO3 had a mass of 1.57 grams. Determine the mass of the H2CO3 produced. Calculate the percentage yield of H2CO3 for the reaction. Show your work or describe the calculation process in detail.
