24-69. Iodine pentoxide is a reagent for the quanti- tative determination of carbon monoxide. The equa- tion for the reaction is 5 CO(g) + I₂O5 (s) → 1₂ (s) + 5 CO₂(g) The iodine produced is dissolved in KI(aq) to form I3(aq) and then determined by reaction with Na₂S₂O3(aq) according to 2S₂O3(aq) + (aq) → 31-(aq) + S₂O² (aq) 6 Calculate the mass percentage of CO(g) in a 56.04-gram sample of air if it requires 10.0 mL of 0.0350 M Na₂S₂O3(aq) to react completely with the Iz (aq) produced.
