If \(M\) is the atomic mass and \(A\) is the mass number, packing fraction is given by
- A \(\frac{A}{M-A}\)
- B \(\frac{A-M}{A}\)
- C \(\frac{M}{M-A}\)
- D \(\frac{M-A}{A}\)
Answer & Solution
Correct Answer
(D) \(\frac{M-A}{A}\)
Step-by-step Solution
Detailed explanation
Packing fraction is equal to the ratio of mass defect to total number of nucleons. i.e. \(\mathrm{PF}=\frac{\text { Mass defect }}{\text { No. of nucleons }}=\frac{M-A}{A}\)
