## Homework Statement

I've attached the question I'm having trouble with.

## Homework Equations

## The Attempt at a Solution

I got an answer of 1.70375 * 10^-3 for the binding energy of a nucleus of uranium 235.

For the third part, "When a uranium-235 nucleus undergoes fission..." I read the value of the binding energy per nucleon for a nucleus half the size of uranium's to be 8.5 *10^-13

So I calculated:

(1.70375 * 10 ^-3) -(2 * 117.5 * 8.5 * 10 ^-13) = difference in total binding energy.

Then I converted this answer in MeV to joules but I got the wrong answer.
