Given,

G = 0.75

Since,    G=\frac{\rho_{\text {alchohol }}}{\rho_{\text {water }}}

\begin{aligned} \rho_{\text {alchohol }} & =G \times \rho_{\text {water }} \\ & =0.75 \times 1000=750  kg / m ^3 \end{aligned}

Weight density will be

\gamma_{\text {alchohol }}=\rho_{\text {alchohol }} \times g

= 750 × 9.81 = 7357.5 N

= 7.357 kN
