Lauryl sulfate is an anion found in cleaners and detergents. Its structure is shown below:

Assuming lauryl sulfate decomposes according to the following reaction:

C₁₂H₂₅SO₄^–(aq) + 18 O₂(aq) → 12 CO₂(aq) + 12 H₂O(l) + H⁺(aq) + SO₄^2–(aq)

Calculate the mass of O₂ required to decompose 15.0 g of lauryl sulfate.
