Detailed Solution

To calculate the molar mass of carbon dioxide ( CO2), we need to add up the atomic masses of all the atoms in the formula.

The atomic masses are:

Carbon (C): 12 g/mol
Oxygen (O): 16 g/mol (there are 2 oxygen atoms in carbon dioxide)

The molar mass of carbon dioxide ( CO2) = ( 12 + 2×16) = 44 g/mol
