    E = 2.7 * 10¹⁵ J

    Explanation:

    Data provided:

    Mass defect = 0.030 Kg

    Now,

    the relation between the mass defect and energy is given as:

    E = mc²

    where,

    E is the energy

    m is the mass

    c is the speed of the light = 3 * 10⁸ m/s

    On substituting the respective values in the above relation, we get

    E = 0.030 * (3 * 10⁸) ²

    or

    E = 2.7 * 10¹⁵ J
