Question

What volume (in L) of water vapor will be

produced from the reaction of 24.65 L of oxygen?
2C2H6(9) + 702(9) — 4CO2(g) + 6H20(9)
Enter

Answer 1

21.13 L

Step-by-step explanation:

Step 1: Write the balanced equation

2 C₂H₆(g) + 7 O₂(g) ⇒ 4 CO₂(g) + 6 H₂O(g)

Step 2: Determine the appropriate volume ratio

Since all the gases are in the same container at the same temperature and pressure, the volume ratio is equal to the molar ratio, because the volume depends on the number of moles. The volume ratio of O₂(g) to H₂O(g) is 7:6.

Step 3: Determine the volume of H₂O produced from 24.65 L of O₂

24.65 L O₂ × 6 L H₂O/7 L O₂ = 21.13 L H₂O
