Chapter 20, Problem 4PE

Interpretation Introduction

Interpretation:

Binding energy per nucleon of carbon $-12$ nucleus, whose mass is 11.996708 u, is to be calculated.

Concept Introduction:

The change between calculated and measured rest mass is called a mass defect.

Nuclear binding energy is determined with the help of Einstein equation.

Mass of a proton and a neutron in atomic mass unit is 1.0072764 u and 1.008664 u respectively.

The speed of light as $2.997\times {10}^8$ m s^-1 and mass of nucleus as $1.6606\times {10}^{-27}$ kg.

Since, $1\text{ u = }1.660653\times {10}^{-27}\text{ kg}$,

The conversion factor is $\frac{1.660653\times {10}^{-27}\text{ kg}}{1\text{ u}}$
