Question

2C6H6(g) + 150₂(g) → 12CO₂(g) + 6H₂O(g)

What volume of water vapor, in liters,
forms at STP when 1 L of C6H6 reacts
with oxygen?
[?] LH₂O
Volume (L) H₂O
Enter

Answer 1

3 L

Step-by-step explanation:

You want to know the volume of water vapor produced at STP when 1 L of C₆H₆ reacts with oxygen.

Reactants

The given balanced reaction equation tells us that 6 moles of water vapor are produced from each 2 moles of C₆H₆. At STP, the volume of water vapor will be 3 times the volume of C₆H₆.

3 liters of water vapor are produced by reacting 1 liter of C₆H₆ with oxygen.
