Question

How many oxygen atoms are there in a half mole quantity of carbon dioxide?

Answer 1

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?
