AfilCa [17]

Answer:

86

Explanation:

The reaction that takes place is:

  • C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

First we <u>convert moles of ethanol to moles of water</u>:

  • 1.6 mol ethanol * \frac{3molH_2O}{1molEthanol} = 4.8 mol H₂O

Then we <u>convert moles of water to grams of water</u>, using its molar mass:

  • 4.8 mol H₂O * 18 g/mol = 86.4 g

So 84.6 grams of water will be produced.
