The molar mass of carbon dioxide would be greater.
The formula for carbon monoxide and carbon dioxide is as follows:-
[tex]Carbon monoxide:-CO\\Carbondioxide:-CO_2[/tex]
Carbon Dioxide (CO₂) is a chemical compound consisting of one carbon atom and two oxygen atoms while Carbon Monoxide (CO) is a chemical compound which contains one carbon atom and one oxygen atom. So, one oxygen atom is more in Carbon Dioxide. So, the molar mass of carbon dioxide would be greater.
