SUMMARY

The discussion focuses on calculating the energy release from the complete fission of 0.001 kg of Uranium-235 (U-235). The energy released is established as 8 x 1010 joules. Participants emphasize using Einstein's mass-energy equivalence formula, E=mc2, and Avogadro's number to determine the number of U-235 atoms and the energy produced per fission reaction. The calculation involves determining the total energy from the fission of all U-235 atoms present in the specified mass.

PREREQUISITES
  • Understanding of nuclear fission processes
  • Familiarity with Einstein's mass-energy equivalence (E=mc2)
  • Knowledge of Avogadro's number and its application in chemistry
  • Basic concepts of atomic structure, including protons and neutrons
NEXT STEPS
  • Calculate the number of U-235 atoms in 0.001 kg using Avogadro's number
  • Research the energy released per fission reaction of U-235
  • Explore the daughter products of U-235 fission
  • Study the implications of mass-energy conversion in nuclear reactions
USEFUL FOR

Students in physics and chemistry, nuclear engineers, and anyone interested in understanding the energy dynamics of nuclear fission reactions.

suppose that 0.001kg of uranium 235 (92 proton number) could be persuded to fission completely

show that the energy release would be 8x10^10 J

thanks

p.s if one could explain how they did it that would be great too thanks

We don't do your homework, we help you do your homework. Do you know the daughter products of the reaction?
 
first part is

nucleaon number/mass number = 92+0=X+54+0 =>38
atomic number/proton number = 235+1=98+X+3 =>136

i can prove the energy release using e=mc^2 and 1.66x10^-27

but its just the last part i can't do which is

suppose that 0.001kg of uranium 235 could be persuded to fission completely

show that the energy release would be 8x10^10 J

heres the question anyway

Determine the number of U-235 atoms in 0.001 kg (think Avogadro's number), then muliply the energy released per fission, and that will give the energy produced by fissioning all the atoms in 0.001 kg.
