Answer:
4.2moles
Explanation:
"The answer to your question is 4.2 moles of H₂O
Explanation:
Data
moles of H₂O = ?
moles of C₂H₆ = 1.4
Balanced chemical reaction
 2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O
Process
To determine the moles of H₂O, use proportions and the coefficients of the balanced chemical reaction.
 2 moles of C₂H₆ 6 moles of H₂O
 1.4 moles of C₂H₆ x
 x = (1.4 x 6) / 2
 x = 8.4/2
 x = 4.2 moles of H₂O"
