The carbon monoxide, CO, in a 20.3 L sample was converted to carbon dioxide, CO2, by passing the gas over iodine pentoxide, I2O5, heated to 150C: 5 CO(g) + I2O5(s)  5 CO2(g) + I2(g) The iodine, I2, gas was collected in an absorber containing 8.25 mL of 0.01101 CM Na2S2O3: I2(g) + 2 S2O3 2(aq)  2 I(aq) + S4O6 2(aq) The excess Na2S2O3 was back-titrated with 2.16 mL of 0.00947 M I2 solution. What is the concentration of CO in the air sample in units of mg CO per liter

Blank allows you to do calculations for situations in which only the amount of gas is constant a)boyle's law b)combined gas law c)ideal gas law d)dalton's law
