Nuclear energy

Level 1

In some nuclear reaction, the mass defect was 3.5 × 1 0 − 28 3.5 \times 10^{-28} kg. How much energy was released by this nuclear reaction? (The velocity of light is 3 × 1 0 8 3 \times 10^8 m/s.)

3.5 × 1 0 − 11 3.5 \times 10^{-11} J 3.15 × 1 0 − 20 3.15 \times 10^{-20} J 3.15 × 1 0 − 11 3.15 \times 10^{-11} J 3.5 × 1 0 − 20 3.5 \times 10^{-20} J
