Answer:
o solve this problem, we need to first write a balanced chemical equation for the reaction between C₂H6 and O₂:
C₂H6 + O₂ → CO₂ + H₂O
From the equation, we can see that for every mole of C₂H6 that reacts, one mole of water is produced.
Next, we need to determine how many moles of C₂H6 we have:
15.9 g C₂H6 × (1 mol C₂H6 / 30.07 g C₂H6) = 0.529 mol C₂H6
Finally, we can use the mole ratio between C₂H6 and H₂O to calculate the number of moles of water produced:
0.529 mol C₂H6 × (1 mol H₂O / 1 mol C₂H6) = 0.529 mol H₂O
Therefore, the answer is A) 0.667 mol (rounded to three significant figures).
