What volume would 2.25 moles of Ne gas occupy at STP?

As we know that one mole of any Ideal gas at standard temperature and pressure occupies exactly 22.4 dm³ volume.

Solution for problem:

When 1 mole Neon (Ne) occupies 22.4 dm³ at STP then the volume occupied by 2.25 moles of Neon is calculated as,

= (22.4 dm³ * 2.25 moles) : 1 mole

= 50.4 dm³ 1dm³ = 1 L

Result:

So, 50.4 dm³ (Liter) volume will be occupied by 2.25 moles of Neon gas if it acts ideally at STP.
