Answer:

#+4#

Explanation:

We start of by giving the oxidation number for hydrogen and oxygen, since we know these already.
So we have 2 hydrogen which each has a charge of #+1#, and we have 3 oxygen which each has a charge of #-2#. If we cancel these out we would have that sulfur should have a charge of #+4# to give a total charge of #0#.
