Calculate the nuclear binding energy of a 32/16 s atom. the measured atomic mass of 32/16 s is 31.972 070 u.

4.993 ×10⁻¹¹ J

Explanation:

The nuclear binding energy is the energy equivalent to the mass defect.

The mass defect is the difference between the mass of a nucleus and the sum of the masses of its nucleons.

Calculate the mass defect

  16 p = 16 × 1.007 28 u =  16.116 48  u

  16 n = 16 × 1.008 67 u =  16.138 72  u

Total mass of nucleons = 32.255 20 u

             - Mass of S-32 = 31.972 070 u

                 Mass defect =  0.283 13   u

Convert the unified atomic mass units to kilograms.

Mass defect

Use Einstein’s equation to convert the mass defect into energy

the answer is definitely c.
