I'm not sure where to begin with this problem, any help would be greatly appreciated!!!

Using the Bohr formula for the energy levels, calculate
the energy required to raise the electron in a hydrogen atom from
n=1 to n=infinite. Express the result for 1 mol H atoms. Because
the n=infinite level corresponds to removal of the electron from the
atom, this energy equals the ionization energy of the H atom.
