The mass of a ⁷₃ Li nucleus is 0.042 u less than the sum of the masses of all its nucleons

The mass of a ⁷₃ Li nucleus is 0.042 u less than the sum of the masses of all its nucleons. The binding energy per nucleon of ⁷₃ Li nucleus is nearly

Options

(a) 46 MeV
(b) 5.6 MeV
(c) 3.9 MeV
(d) 23 MeV

Correct Answer:

5.6 MeV

Explanation:

B.E. = 0.042 x 931 = 42 MeV
Number of nucleons in ⁷₃Li is 7.
B.E. / nucleon = 42/7 = 6 MeV
app. 5.6 MeV
