Question

calculate the energy in Jule required to convert all the atoms of Na+ ions present 2.3 mg of sodium vapour ionization enthalpy of sodium 495 Kj mol¹.



plz don't give me time waist answere​

Answer 1

Explanation:

Ionisation energy: The Minimum energy required to remove most loosely held outer most shell electron in the ground state from an isolated gaseous atom is known as ionization potential.

Here,

No. of moles of sodium =

23

2.3×10

−3

=0.1×10

−3

mole

So energy needed to convert into ions = 495×10

3

(0.1×10

−3

)=49.5 joule
