The mass of ₇ ~N ¹⁵ is 15.00011 amu , mass of ₈ O ¹⁶ is 15.99492 amu and m_ p =1.00783 amu. Determine binding energy of last proton of ₈ O ¹⁶ .

Options

  1. A2.13 MeV
  2. B0.13 MeV
  3. C10 MeV
  4. D12.13 MeV

Correct answer

D. 12.13 MeV

Step-by-step solution

M ( ₈ O ¹⁶ )= M ( ₇ ~N ¹⁵ )+1 ~m _ p binding energy of last proton =M (N¹⁵ )+m_ P -M ( ₁ O¹⁶ )=15.00011+1.00783-15.99492=0.01302 amu =12.13 MeV
