The atomic mass of ₆ C ¹² is 12.000000 u and that of ₆ C ¹³ is 13.003354 u . The required energy to remove a neutron from ₆ C ¹³ , if mass of neutron is 1.008665 u , will be:

Options

  1. A62.5 MeV
  2. B6.25 MeV
  3. C4.95 MeV
  4. D49.5 MeV

Correct answer

C. 4.95 MeV

Step-by-step solution

₆ C ¹³+ Energy ₆ C ¹²+ ₀ n ^1 Mass defect, m =(12.000000+1.008665)- 13.003354 =-0.00531 u Energyrequired = m 931.5=0.00531 931.5 MeV =4.95 MeV
