If M is the atomic mass and A is the mass number, packing fraction is given by

Options

  1. AM M-A
  2. BM-A A
  3. CA M-A
  4. DA-M A

Correct answer

B. M-A A

Step-by-step solution

Packing fraction is the ratio of mass defect to the number of nucleons. Mass defect is the difference in the actual isotopic mass (M) and mass number (A) . Packing fraction = M-A A where, A is mass number or number of nucleons.
