Answer 2

NAOH + CO₂ — > Na₂CO₃ + H₂O

Mole ratio :

1 : 2

We need 2 moles of NaOH to convert one mole of CO₂ to Na₂CO₃.

Moles of NaOH :

20 / 40 = 0.5 moles

Moles of CO₂ :

0.5/ 2 = 0.25

Moles of CO are:

1 - 0.25 = 0.75 moles.

Oxidation of CO :

CO + 1/2 O₂ —> CO₂

Mole ratio is 1 : 1

Moles of CO₂ formed are 0.75 moles.

Thus is half the moles of NaOH required.

NaOH required is thus :

2 × 0.75 =1.5 moles

1 mole — > 40 g

1.5 moles —>?

1.5 × 40 = 60g

60 g is required
