Answer :
Answer:
Binding energy =159.6 MJ/mole
Explanation:
Given that
Photons energy = 198.2 MJ/mole
Kinetic energy of electrons = 38.6 MJ/mole
We know that the relationship between photons energy,kinetic energy of electron and binding energy
Photons energy = Binding energy + Kinetic energy of electrons
So
Binding energy = Photons energy - Kinetic energy of electrons
Now by putting the values
Binding energy =198.2 - 38.6 MJ/mole
Binding energy =159.6 MJ/mole
