The molar mass of CO2 is:

Explanation:

The molar mass of CO₂ can be calculated by taking the sum of gram atomic masses of its constituent elements i.e. carbon(C) and oxygen (O).

It is calculated as follows:

Molar mass of CO₂= (12x1 + 16x2) gm

= 44 gm

Final Answer:

Hence, the molar mass of CO₂ is 44gm.
