    Answer:
    m = 2 * 10u207bu00b3kg

    Explanation:
    To answer this question, we will need to use Einstein’s formula:
    E = mcu00b2
    where:
    E is the energy converted = 1.8 * 10u00b9u2074 J
    m is the mass that we want to get
    c is the speed of light = 3 * 10u2078 m/sec

    Substitute with the givens in the above formula to get the mass as follows:
    1.8 * 10u00b9u2074 = m * (3 * 10u2078)u00b2
    m = 2 * 10u207bu00b3 kg

    Hope this helps 🙂
