Quizplus · Accepted Answer

The energy released can be calculated using Einstein's equation, E=mc^2, where m is the mass lost (4.8 × 10^-28 kg) and c is the speed of light (3.0 × 10^8 m/s). Plugging in the values, E = (4.8 × 10^-28 kg)(3.0 × 10^8 m/s)^2 = 4.32 × 10^-11 J, which rounds to 4.3 × 10^-11 J.
