How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 88.1 molesmoles of water vapor?

Express your answer with the appropriate units.

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
