Calculating Energy Release from Fission of 0.001kg Uranium 235

[dirac1]

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.
