Sulfur oxide is not a specific compound, but rather a general term for any compound containing sulfur and oxygen.

To give you a molecular formula, you need to specify which sulfur oxide you are referring to. There are several common ones:

* Sulfur dioxide (SO₂) : This is the most common sulfur oxide.

* Sulfur trioxide (SO₃): This is another common sulfur oxide.

If you provide me with more information about the specific sulfur oxide you're interested in, I can give you a more precise answer.
