Question

calculate binding energy of o nucleus . given masses of proton,neutron and oxygen nucleus as 1.00782, 1.00867 and 15.99491 a.m.u. respectively..​

Answer 1

Answer:

7.48

Explanation:

Nuclear reaction : 7p+7n→

7

14

N

Mass defect ΔM=7m

p

+7m

n

−m

nucleus

∴ ΔM=7(1.00783)+7(1.00867)−14.00307 amu

⟹ ΔM=0.11243 amu

Thus binding energy E=ΔM×931.5 MeV

∴ E=0.11243×931.5=104.73 MeV

Binding energy per nucleon =

14

104.73

=7.48 MeV
