** Urgent! ** A 8.13-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 5.27 grams.

1. Determine the mass of the H2CO3 produced.

2. Calculate the percentage yield of H2CO3 for the reaction.
