Given :-
Mass of the nucleus,

M = A m_{p}

Volume of the nucleus,

V = \frac{4}{3} π R_{0}^{3} A

Density of the matter,

d = \frac{M}{V} = \frac{A m _{p}}{\frac{4}{3} π R _{0}^{3} A}

= \frac{3 m _{p}}{4 \times π R _{0}^{3}}

= \frac{3 \times 1.007276}{4 \times 3.14 ( 1.1 ) ^{3}}

= 3 \times 1 0^{17} kg / m^{3}

Specific gravity of the nuclear matter

= \frac{Density of matter}{Density of water}

∴

Specific gravity

= \frac{3 \times 1 0 ^{17}}{1 0 ^{3}} = 3 \times 1 0^{14} kg / m^{3}
