    7.8 x 10⁶ J

    Explanation:

    using the Mass-Energy equivalence formula,

    i. e E = mc²

    where

    E = energy

    m = mass = given as 0.026 kg

    c = speed of light = which we will assume to be 3 x 10⁸ m/s

    substituting the above into the formula

    E = mc²

    = 0.026 x (3 x 10⁸) ²

    = 0.026 x (9 x 10¹⁶)

    = 2.34 x 10¹⁵ J
