Suppose Missy bon bon have 20.3 L sample of gas that contains an impurity, CO. The sample was then passed over iodine peroxide and heated to 150 degrees celsius to convert the impure substnace to Carbon dioxide, CO2. The iodine distilled at this temperature was collected in an absorber containing 8.25 mL of 0.01101 M NazS203. The excess Na S203 was back-titrated with 2.16 mL of 0.009471 12 solutions. Calculate the number of milligrams of CO (FW 28.01) per liter of sample. Pertinent reactions 1205 (s) 5CO (g) + 5CO2 (g) + 12 (g) 12 (aq) 2S2032- (aq) 21-(aq) + S4062-(aq)
