We are asked to calculate the mass percent composition of each constituent element of sulfurous acid.

sulfurous acid → H_{2}SO_{3}

Molar mass H_{2}SO_{3} = 82.09 g/mol

Molar mass H = 1.01 g/mol

Molar mass S = 32.07 g/mol

Molar mass O = 16.00 g/mol

Calculate the mass percent composition of each constituent element of sulfurous acid.
