    88.1 moles of H₂

    Explanation:

    Let's make the reaction:

    H₂ (g) + CO₂ (g) → H₂O (g) + CO (g)

    Ratio is 1:1

    Therefore, 1 mol of hydrogen reacts with 1 mol of carbon dioxide to produce 1 mol of water and 1 mol of carbon monoxide.

    In conclusion, 88.1 moles of water must be produced by 88.1 moles of H₂

    The reaction can also be written as an equilbrium

    H₂ (g) + CO₂ (g) ⇄ H₂O (g) + CO (g) Kc
