Sulfurous acid is unstable in aqueous solution and gradually decomposes to water and sulfur dioxide gas (which explains the choking odor associated with sulfurous acid solutions).
H2SO3(aq) → H20(1) + SO2(g)
If 4.05 g of sulfurous acid undergoes this reaction, what mass of sulfur dioxide is released?
