Energy of an electron in the ground state = -2.18 x 10-18.
Energy required for removal of the electron = 0 -(-2.18 x 10-18 ) =2.18 x 10-18 J.
This is the energy required to remove the electron from one atom of hydrogen in ground state. The energy required to remove electron from one mole (6.022 x 1023atoms) will be = 2.18 x 10-18 x 6.022 x 1023 = 13.12 x 105 J/mol
