Ответ:
144.08 g of H₂O
Explanation:
The balance chemical equation for the synthesis of water is as follow;
2 H₂ + O₂ → 2 H₂O
Step 1: Find out moles of H₂O produced as;
According to balance chemical equation,
1 mole of O₂ produced = 2 moles of H₂O
So,
4 moles of O₂ will produce = X moles of H₂O
Solving for X,
X = 4 mol × 2 mol / 1 mol
X = 8 moles of H₂O
Step 2: Calculate Mass of H₂O as;
Mass = Moles × M.Mass
Mass = 8 mol × 18.01 g/mol
Mass = 144.08 g of H₂O
