Answer :
At STP, or standard temperature and pressure, 1 mol of any gas will take up 22.4 liters of space. Assuming STP, 4.5 moles of H2 will take up 100.8L.
The volume of 4.5 moles of H₂ is 100.8 dm³
From the question,
We are to determine the volume of 4.5 moles of H₂
Let the volume be x
Recall:
1 mole of a gas occupies 22.4 dm³ at STP
Now,
If there are 22.4 dm³ in 1 mole of H₂
Then,
There will be x dm³ in 4.5 moles of H₂
∴ x = [tex]\frac{22.4 \times 4.5}{1}[/tex]
x = 100.8 dm³
Hence, the volume of 4.5 moles of H₂ is 100.8 dm³
