Answer:
This is the ionization energy for a single atom. To find the normally quoted ionization energy, this value is multiplied by the number of atoms in a mole of hydrogen atoms (the Avogadro constant) and then dividing by 1000 to convert joules to kilojoules.

Answer:
Given no. of atoms = Avogadro's no. of atoms = N
A
=6.023×10
23
Given that
2
N
A
atoms are ionized, i.e.,
Ionization energy of
2
N
A
atoms of gas X = ΔH
∴ Ionization energy of 1 atom of gas X =
(
2
N
A
)
ΔH
=
N
A
2.ΔH
Hence, Ionisation energy of gas X is
N
A
2.ΔH/NA
.
