The conversion factor to change moles of CO2 to grams of CO2 is the molar mass of CO2.

Here's how to calculate it:

* Find the atomic masses of Carbon (C) and Oxygen (O) from the periodic table:

* Carbon (C): 12.01 g/mol

* Oxygen (O): 16.00 g/mol

* Calculate the molar mass of CO2:

* CO2 = (1 x 12.01 g/mol) + (2 x 16.00 g/mol) = 44.01 g/mol

Therefore, the conversion factor is 44.01 g/mol.

To convert moles of CO2 to grams of CO2, multiply the number of moles by 44.01 g/mol.
