SO2(g) + H2O(l) → H2SO3(l)
mols H2SO3 needed = grams/molar mass = 29.36/82 = estimated 0.3
1 mol SO2 provides 1 mol H2SO3; therefore, approx 0.3 mol H2SO3 will need approx 0,3 mol SO2.
grams SO2 = mols SO2 x molar rmass SO2 = ? Remember my numbers are estimates.
Elemental sulfur can be converted to sulfur dioxide by combustion in air. Sulfur dioxide will react with water to form sulfurous acid (see balanced equation below).
SO2(g) + H2O(l) → H2SO3(l)
What mass of sulfur dioxide is needed to prepare 29.36 g of H2SO3(l)?
A. 0.4582 g
B. 29.36 g
C. 37.61 g
D. 22.91g
