## Homework Statement

Find the binding energy per nucleon of

238

92 U in MeV

## Homework Equations

ΔM= ideal mass - atomic mass

Ebind= ΔM * 931.5

## The Attempt at a Solution

first i found the diference in mass from ideal weight and atomich weight which is 1.98499. then i multiplied it by 931.5 which gives me a total binding energy of 1849.0181 MeV.

Now, i understand that a nulceon is a pair made of a proton and a neutron so i should divide my answer by the number of nucleons in the atom. but there are more neutrons than protons in U so i dont know what should i divide by!!
