Answer:
10.1 L
Step-by-step explanation:
At STP (meaning T = 273 K and P = 1 atm) one mol of any given gas will occupy 22.4 liters.
With the above information in mind, we can calculate how many liters will 0.45 moles of water vapor occupy:
- 0.45 mol * 22.4 L / mol = 10.1 L
Meaning that if 0.45 moles of water are produced at STP, 10.1 liters of water would be produced.
