WebSep 8, 2024 · The change in energy that accompanies a nuclear reaction can be calculated from the change in mass using the relationship 1 amu = 931 MeV. The energy released by the decay of one atom of 14 C is thus ( − 1.68 × 10 − 4amu)(931MeV amu) = − 0.156MeV = − 156keV Example 21.6.1 WebSep 12, 2024 · Calculate the energy released in the following rare spontaneous fission reaction: U238 → Sr95 + Xe140 + 3n, The atomic masses are m(238U) = 238.050784u, m(95Sr) = 94.919388u, m(140Xe) = 139.921610u, and m(n) = 1.008665u.
