Nuclear Mass Defect and Binding Energy

If the binding energy per nucleon for ${}_3{}^7\mathrm{Li}$ and ${}_2{}^4\mathrm{He}$ nuclei are $5.60 \mathrm{MeV}$ and $7.06 \mathrm{MeV}$ respectively, then, in the reaction
$\mathrm{p}+{}_3{}^7\mathrm{Li}⟶2 \left({}_2{}^4\mathrm{He}\right)$ energy of proton must be

If the binding energy of the electron in a hydrogen atom is $13.6\mathrm{eV},$ the energy required to remove the electron from the first excited state of ${\mathrm{Li}}^{++}$ is

If the mass-energy equivalence is taken into account, when water is cooled to form ice, the mass of water should

The masses of neutron and proton are $1.0087 \mathrm{a}.\mathrm{m}.\mathrm{u}.$ and $1.0073 \mathrm{a}.\mathrm{m}.\mathrm{u}.$, respectively. If the neutrons and protons combine to form a helium nucleus (alpha particle) of mass $4.0015 \mathrm{a}.\mathrm{m}.\mathrm{u}.$, the binding energy of the helium nucleus will be $(1 \mathrm{a}.\mathrm{m}.\mathrm{u}.=931 \mathrm{MeV})$

The mass equivalent of $931\mathrm{MeV}$ energy is

The mass of a ${}_3{}^7\mathrm{Li}$ nucleus is $0.042 \mathrm{u}$ less than the sum of the masses of all its nucleons. The binding energy per nucleon of ${}_3{}^7\mathrm{Li}$ nucleus is nearly,

One kilogram of mass is completely converted into energy. The heat produced in kilo calories will be,

The energy equivalent to $1 \mathrm{amu}$ in $\mathrm{MeV}$ will be,

If the total binding energies of ${}_1{}^2\mathrm{H}\text{, }{}_2{}^4\mathrm{He}\text{, }{}_{26}{}^{56}\mathrm{Fe} \mathrm{and} {}_{92}{}^{235}\mathrm{U}$ nuclei are $2.22 \mathrm{MeV}\text{, }28.3 \mathrm{MeV}\text{, }492 \mathrm{MeV}$ and $1786 \mathrm{MeV}$, respectively. Identify the most stable nucleus of the following.

When the number of nucleons in nuclei increases, the binding energy per nucleon
