We know,
$\left[\frac{1}{\rho_2}-\frac{1}{\rho_1}\right]=-\frac{P}{B}$ $\left\{\begin{array}{l}\text { Where } \\ P=2 \times 10^8 \,N / m ^2 \\ B=8 \times 10^9 \,N / m ^2 \\ \rho_1=11.4 \,g / cc \\ \rho_2=?\end{array}\right.$
Substitute value's
$\left[\frac{1}{\rho_2}-\frac{1}{114}\right]=-\frac{2 \times 10^8}{8 \times 10^9}$
After solving, we get
$\rho_2=11.7 \,g / cc$
