Step 1

Given information:

Number of moles of CO(g) = 1.0 mole

Number of moles of CO2(g) = 1.0 mole

Step 2

Mole is the amount of the substance that contains the same number of particles or atoms or molecules.

Step 3

As, carbon monoxide (CO) is a compound having one carbon atom and an oxygen atom whereas, carbon dioxide (CO2) is a compound having one carbon atom and two o...
