When is the oxidation state for a molecule 0?

The oxidation state is zero for elements in their free (uncombined) state (ex: Zn(s), Al(s)), including those found in nature as diatomic elements (ex: O2, N2, H2).

I'm assuming you meant for the oxidation state for oxygen... Oxygen typically has an oxidation number of -2 when in a molecule. However, when it is by itself and has no overall charge (O2) it is zero.
