2H2(g) + O2(9) - 2H20(9)
How many liters of Hy are required to form 5 moles of H20 at STP?
)
A)
)
11.2 liters
B)
22.4 liters
44.8 liters
D
112 liters

Answer 1

• 2 moles H_2 required for 2 mol H_20
• 1 mol of H_2 required for 1 mol H_2O
• 5mol of H_2 required for 5mol H_20

Now

At STP any gas weighs 22.4L

Volume of H_2

• 22.4+(5)
• 112L
