Question

What is the average binding energy per nucleon for an O-16 nucleus with a mass defect of 0.136 amu? (1 amu= 1.66 x 10-27 kg; 1 J = 1 kg m2/s2) Answer 2.03 x 10-11 J 1.27 x 10-12 J 7.53 x 10-20 J 4.71 x 1012 J

Answer 1

Since you know the mass defect, use \( E = mc^2\) to find the binding energy per mole. Then find the binding energy per atom, then per nucleon, since there are 16 nucleons per atom of \(^{16}O\)

Answer 2

@JFraser how do I find the binding energy

Answer 3

use the equation \(E =mc^2\), since you know the mass defect (m), and the speed of light is constant, \(3.0*10^8 m/s\)

Answer 4

you'll have to convert the mass from amu into kilograms, but it gives you that conversion
