Meq. of CO2 in mixture = 
Mole of CO2 in mixture
Mole of CO in mixture = 3/4
If this CO is completely oxidised to CO2 then mole of CO2 formed = 3/4
Mole of NaOH required
= 2 x mole of CO2= 2x1=2
Wt. of NaOH required=2x40=80 g
Mole of CO2 in mixture
Mole of CO in mixture = 3/4
If this CO is completely oxidised to CO2 then mole of CO2 formed = 3/4
Mole of NaOH required
= 2 x mole of CO2= 2x1=2
Wt. of NaOH required=2x40=80 g

Given Information:
- One mole of a mixture of CO and CO2 requires 20 g of NaOH for complete conversion of all the CO2 into Na2CO3.
- The question asks for the amount of NaOH required for the complete oxidation of the mixture to CO2.
Solution:
Step 1: Determine the Molar Masses
- Molar mass of CO = 28 g/mol
- Molar mass of CO2 = 44 g/mol
- Molar mass of NaOH = 40 g/mol
- Molar mass of Na2CO3 = 106 g/mol
Step 2: Calculate the Amount of NaOH Required for CO2 Conversion
- For complete conversion of CO2 to Na2CO3, 44 g of CO2 requires 40 g of NaOH.
- Since the total amount of CO + CO2 is one mole, which means the amount of CO2 in the mixture is 0.5 moles.
- Therefore, 0.5 moles of CO2 would require 0.5 * 40 g = 20 g of NaOH.
Step 3: Final Answer
- The amount of NaOH required for the complete oxidation of the mixture to CO2 is 20 g.
- Therefore, the correct answer is option b) 80 g.
- One mole of a mixture of CO and CO2 requires 20 g of NaOH for complete conversion of all the CO2 into Na2CO3.
- The question asks for the amount of NaOH required for the complete oxidation of the mixture to CO2.
Solution:
Step 1: Determine the Molar Masses
- Molar mass of CO = 28 g/mol
- Molar mass of CO2 = 44 g/mol
- Molar mass of NaOH = 40 g/mol
- Molar mass of Na2CO3 = 106 g/mol
Step 2: Calculate the Amount of NaOH Required for CO2 Conversion
- For complete conversion of CO2 to Na2CO3, 44 g of CO2 requires 40 g of NaOH.
- Since the total amount of CO + CO2 is one mole, which means the amount of CO2 in the mixture is 0.5 moles.
- Therefore, 0.5 moles of CO2 would require 0.5 * 40 g = 20 g of NaOH.
Step 3: Final Answer
- The amount of NaOH required for the complete oxidation of the mixture to CO2 is 20 g.
- Therefore, the correct answer is option b) 80 g.
