Q. The mass of the nucleus ${}_7{N}^{14}$ is $14.00000amu$. Calculate the binding energy per nucleon of ${}_7{N}^{14}$ in MeV. Mass of proton$=1.00759amu$, mass of neutron$=1.00898amu$ and $1amu=931MeV.$

Q. Calculate the nuclear binding energy per nucleon of ${}_6^{12}C$ from the following data:
Given mass of proton $\left(m_p\right)=1.00758$ amu
mass of neutron $\left(m_n\right)=1.00893$ amu
mass of electron $\left(m_e\right)=0.00055$ amu
Isotopic mass of ${}^{12}C=12.00000$ amu. Take $1amu=931$ MeV
Plan from the mass defect $△m$ (amu), binding energy $=△m\times 931$ MeV
binding energy per nucleon$=\frac{△m\times 931}{numberofnucleons}$
