Total binding energy per nucleus

A nucleus in a radioisotope decay log has nucleon number \(70\) and binding energy per nucleon \(7.5\,\text{MeV}\). Calculate total binding energy. Use the diagram labels before calculating the requested value. Enter the numerical result and choose the interpretation that matches the quantum or nuclear physics.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
