Ответ:
3 mol
Explanation:
Given data:
Moles of hydrogen = 3 mol
Moles of oxygen = 2 mol
Yield of reaction = 80%
Moles of water produced = ?
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Now we will compare the moles of water with both reactants.
H₂ : H₂O
2 : 2
3 : 3
O₂ : H₂O
1 : 2
2 : 2×2 = 4
Hydrogen produced less number of moles of water so it will limiting reactant.
So number of moles of water produced are = 3 mol
