Question

The average binding energy per nucleon of the  nucleus is 4.0 MeV. What is the total energy required to separate the nucleons of one nucleus of ?

A.  53 MeV

B.  60 MeV

C.  113 MeV

D.  173 MeV

Answer 1

Binding Energy per nucleon = Total BE / Number of Nucleons

Total Binding energy + BE per nucleon * Number of nucleons

In this case number of nucleons = 15

So Energy required = 4 * 15 = 60 MeV

¹⁵₈ O has 8 protons and 15 Nucleons
