Calculate the energy released by a nucleus of uranium-235 if it splits into a barium-141 nucleus and a krypton-92 nucleus according to the equation above.

Strategy Einstein’s equation (E = mc ²) relates the energy released to the difference in mass between the fissile uranium nuclide and the resulting fission products.

The fission reaction is described by the equation above, so we just need to account for the masses of all participating particles.
