Calculating Energy Release from Nuclear Fission

[jinx007]

The binding energy per nucleon of each nucleus is as follows.

235
U : 1.2191 x 10^-12 J
92144
Ba : 1.3341 x 10^-12 J
5690
Kr : 1.3864 x 10^-12 J
36Use 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
