Hi(adsbygoogle = window.adsbygoogle || []).push({});

I have been asked in a past exam paper to estimate the energy released by the fission of one^{235}U nucleus. I am given the mass of a^{235}U nucleus and also^{141}Cs nucleus and^{93}Rb nucleus in the 'Useful constants and formula' section of the exam so I wondered if I had to use these, although obviously 141 and 93 do not sum to 235 so I wondered if there was a method to estimate the energy released by a fission without using mass differences etc, like if you just used an estimate of the energy released per nucleon in fission or something? Many Thanks
