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
