Mass-Energy Relation — Prelims Questions

Calculate the energy released in MeV when $1\,\text{amu}$ of mass is completely converted into energy. (Given: $c = 3 \times 10^8\,\text{m/s}$, $1\,\text{amu} = 1.66 \times 10^{-27},\text{kg}$, $1\,\text{eV} = 1.6 \times 10^{-19},\text{J}$)

The mass of a proton is $1.007276\,\text{u}$ and that of a neutron is $1.008665\,\text{u}$. If the mass of a $^4_2\text{He}$ nucleus is $4.00150\,\text{u}$, what is the mass defect for the Helium nucleus?

If the binding energy per nucleon for a nucleus is $7.5\,\text{MeV}$ and its mass number is $10$, what is the total binding energy of the nucleus?

Which of the following statements about mass-energy relation is INCORRECT?

In a nuclear reaction, the total mass of the products is $2.00\,\text{u}$ less than the total mass of the reactants. How much energy is released in this reaction? (Given: $1\,\text{u} \cdot c^2 = 931.5\,\text{MeV}$)

The binding energy per nucleon curve peaks around which mass number, indicating maximum stability?
