44 gm of CO2 = 6.023 x 1023 atoms in it.
So, 88 gm of CO2 = 1.2046 x 1024 atoms in it.
The second part of the question is invalid. This is because in CO, oxygen is unimolar. you cannot have a case where the atoms for oxygen in it can be 1.2046 x 1024 atoms in number, which is possible only if it is bimolecular. Pls review and also understand the question that you are asking.
