Moles give a consistent method to convert between atoms & molecules and grams. Also, one mole of anything will have 6.02e23 molecules of the substance, thus making it more consistent. One gram of O2 does not have the same amount of molecules as one gram of CO2. It's basically to keep measurements consistent and reproducible, while knowing the amount of molecules as well.
