Answer: 8.03mol
Explanation: We use Avogadro's number of
6.022×10^23 molecules per mole to calculate the number of molecules from the number of moles represented by 225 g
of carbon dioxide. The gram-molecular weight of carbon dioxide can be calculated from the atomic weights for carbon and oxygen (two of them in CO2) given in a Periodic Table of the Elements.
Hope that helps! Have a good day :)
