Question #2465d

Answer 1

The volume would be `274` L.

Explanation:

[Step1] Find the amount of substance.

A mole of ideal gas has `6.02xx10^23` molecules.(This is the Avogadro's number.)
Since `Ne` is a monoatomic molecule, `7.28xx10^24` atmos are equivalent to `7.28xx10^24` molecules, and that is `(7.28xx10^24)/(6.02xx10^23)=12.09` moles.

[Step2] Find the volume.
A mole of ideal gas in STP(`0`℃, `1.0xx10^5`Pa) occupies `22.7` L.
So, the volume of `12.09` moles of Ne in STP is `12.09xx22.7=274.443≒274` L.
