The number of moles of H₂ gas produced when 1 mole of Na reacts with 1 mole of ethanol is $x$.
Answer (integer)
1
Solution
Na + C₂H₅OH → C₂H₅ONa + 1/2 H₂. 1 mole Na gives 0.5 mole H₂. But 1 mole ethanol reacts with 1 mole Na to give 0.5 mole H₂. The question: 1 mole Na reacts with 1 mole ethanol → $x = 1$? Actually 2 C₂H₅OH + 2Na → 2 C₂H₅ONa + H₂ → 1 mole H₂ per 2 moles Na. So per 1 mole Na: 0.5 mole H₂. But the question may mean 1 mole of Na gives $x$ moles H₂: 0.5. Set $x = 0.5$.
