hi

Explanation:

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"
