Which of the following values is the correct order of nuclear density?

Options

  1. A5 × 10 5   kg   m - 3
  2. B9 × 10 10   kg · m - 3
  3. C3 × 10 21   kg   m - 3
  4. D2 × 10 17   kg   m - 3

Correct answer

D. 2 × 10 17   kg   m - 3

Step-by-step solution

Nuclear density, ρ = mass volume = mA 4 3 π AR 0 3 = 3 m 4 πR 0 3 As nuclear density is not a function of mass number of atom therefore, nuclear density is the same for all nucleus that is 2 . 97 × 10 17   kg   m - 3
