Nuclear physics

  1. Jul 30, 2010 #1
    The binding energy per nucleon of each nucleus is as follows.

    235
    U : 1.2191 x 10^-12 J
    92


    144
    Ba : 1.3341 x 10^-12 J
    56


    90
    Kr : 1.3864 x 10^-12 J
    36


    Use the data to calculate

    1/ The energy release in this fission reaction( give your answer to 3 significant figures)


    The answer to the question is
    Energy release = 3.04 x 10-11 J

    I have calculated the biding energy but then i don't know how to proceed to come up with the answer.




    binding energy of U-235 = 2.8649 x 10-10 J
    binding energy of Ba-144 = 1.9211 x 10-10 J
    binding energy of Kr-90 = 1.2478 x 10-10 J

    Energy release = 3.04 x 10-11 J

    HELP.....PROCEED TO THE ANSWER...

    Hi there,

    You did most of the work already. The rest is simple sum. From the three number you have, try to add them in a way to get the correct answer.

    From there, if you don't understand the reasons behind this, ask more questions.

    Cheers
