    Answer:

    Explanation:

    Using the formula : E = mc²

    Where m = mass = 6.8 × 10^-6 kg

    c = speed of light = 3 ×10^8 m/s

    The amount of joules of energy that would be produced equals :

    Plugging in our values :

    E = mc²

    E = (6.8 × 10^-6) kg × (3 ×10^8)²m/s

    E = (6.8 × 10^-6) kg × 9 × 10^16 m/s

    E = 61.2 × 10^(-6 + 16)

    E = 61.2 × 10^10 J
