Answer:

In a #1/2# mole of #CO_2#? Well, clearly there are 1 mole of oxygen atoms.

Explanation:

In one mole of #CO_2#, clearly there are #2# mole of oxygen atoms; note that I speak in terms of atoms, and not molecules, and I am perfectly free to do so in the context of this question.

So in a #1/2# mole of #CO_2#, there are #1# mol of oxygen atoms. What are the masses of each quantity?
