The percentage yield of carbonic acid is 66 percent.
How to find percentage yield?
The percentage yield of the carbonic acid can be found as follows:
NaHCO₃ → Na₂CO₃ + H₂CO₃
Hence, 2.36g sample of NaHCO₃ was thermally decomposed to generate 1.57g of carbonic acid (H₂CO₃)
Using law on conservation, the mass of the reactant is equals to the product.
Therefore,
percentage yield of carbonic acid = 1.57 / 2.36 × 100
percentage yield of carbonic acid = 157 / 2.36
percentage yield of carbonic acid = 66.2447257384
percentage yield of carbonic acid = 66 %
