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 correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
