    Answer:

    gO₂ = 32.32 g

    Explanation:

    In this case, let’s write the general equation:

    2H₂ + O₂ ——-> 2H₂O

    In this case, we can use the 1° law, which is mass conservation. If the product has 36.36 g of water, then in the reactants we should have the same 36.36 g.

    According to this, we already have 4.04 of hydrogen, then the remaining to reach the 36.36 g would be:

    gO₂ = 36.36 – 4.04

    gO₂ = 32.32 g

    Hope this helps
