Question

Quizplus · Accepted Answer

The balanced chemical equation for the reaction is:2H₂ + O₂ → 2H₂OFrom the equation, we can see that 2 moles of H₂ react with 1 mole of O₂ to produce 2 moles of H₂O.Therefore, 5.0 mol of H₂ will react with 2.5 mol of O₂ to produce 5.0 mol of H₂O.The molar mass of H₂O is 18.0 g/mol.Therefore, 5.0 mol of H₂O will have a mass of 5.0 mol x 18.0 g/mol = 90.0 g.So, the correct answer is A) 90 g.
