Question

Find the number of moles of water that can be formed if you have 130 mol of hydrogen gas and 60 mol of oxygen gas.

Answer 1

Answer:

130 moles of water might be produced by the reaction.

Explanation:

We state the equation for production of water:

2H₂(g) + O₂ (g) → 2H₂O (l)

Moles of hydrogen: 130

Moles of oxygen: 60

We state that the limting reactant is the oxygen

For 2 moles of hydrogen, we need 1 mol of oxygen

For 130 moles of hydrogen, we would need 65 moles, and we only have 60. Ratio is 2:1

1 mol of O₂ can produce 2 moles of water

Then, 60 moles of O₂ will produce (60 . 2) /1 = 130 moles
