Total binding energy per nucleus

A nucleus in a stellar core model has nucleon number \(62\) and binding energy per nucleon \(8.2\,\text{MeV}\). Calculate total binding energy. 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.
