On removing an electron the Helium atom becomes a single electron atom, applying Bohr's Model ,the energy of the single electron is given by
-13.6z2n2 (where z is atomic no. and n is the no. of the shell in which the electron resides).
Thus ,
the energy comes out to be -13.641, which is -54.4.
So ,
the total energy required to remove both the electrons will be 24.6+54.4=79.0
