A hypothetical method uses the following equation to determine the amount of SO2 in the gas by passing a sample through a sodium carbonate-containing vessel which removes the SO2.
Na2CO3(aq) + H2O(l) + 2 SO2(g) → 2 NaHSO3(aq) + CO2(g)
How much Na2CO3 in moles is required for the removal of 6.29×10−6 mol of SO2?
