One mole of mixture of CO and CO2 requires exactly 20gm. NaOH to convert all the CO2 into Na2CO3. How many more grams of NaOH would it require for conversion in to Na2CO3, if the mixture is completely oxidised into CO2

Number of moles of CO2 and CO in the mixture = 1Weight of NaOH required to convert all CO2 into Na2CO3 = 20g moles of CO in the initial mixture = (1 - 0.25)= 0.75Let us assume that all this CO gets Oxidized to CO2 and then reacts with NaOH to get converted to Na2CO3X2 = 0.75 molesmoles of CO2 formed due to oxiditation of 'CO' = 0.75= 60gWt of NaOH required to neutralize the CO2 obtained by the oxidation of CO = 60g
