    4.563 times more energy.

    Step-by-step explanation:

    The ionization energy of hydrogen is 1312.0 kJ·mol⁻¹.

    The second ionization energy of Li (the first ionization energy of Li⁺) is 7298.1 kJ·mol⁻¹.

    Ratio = 7298.1/1312.0

    Ratio = 5.563

    The ionization energy of Li⁺ is 5.563 times as much as, or 4.563 times more than, the ionization energy of H.
