Question

Atomic mass of carbon is 13.00335 Amu and it’s mass number is 13.binding energy of neutron present in nucleus

Answer 1

Given:

Atomic mass of carbon is 13.00335 amu and it’s mass number is 13.

To Find:

What is the binding energy of neutron present in nucleus?

Solution:

Given that actual mass of nucleus is:

Actual mass of nucleus = 13.00335 amu

Predicted mass of nucleus is given below:

Predicted mass of nucleus = 13 amu

We know the formula of mass defect of nucleus:

Mass defect =Actual mass of nucleus - Predicted mass of nucleus

On putting respective in above equation:

Mass defect = 13.00335 - 13

Mass defect = 0.00335 amu

We know mass defect of 1 amu of nucleus is equivalent to 931 MeV of binding energy:

Binding energy = Mass defect ×931   MeV

Binding energy = 0.00335 ×931   MeV

Binding energy = 3.11885 MeV

Means binding energy of neutron present in nucleus is 3.11885 MeV.
