Mass of the carbon tetrachloride = $15.9 \mathrm{g}$

Volume of carbon tetrachloride= $10 \mathrm{ml}$

Density of carbon tetrachloride = $\frac{\mathrm{Mass} \mathrm{of} \mathrm{carbon} \mathrm{tetrachloride}}{\mathrm{Volume} \mathrm{of} \mathrm{carbon} \mathrm{tetrachloride}}$

Density of carbon tetrachloride = $\frac{15.9}{10}=1.59$

Hence, density of carbon tetrachloride is $1.59 \mathrm{g}·{\mathrm{ml}}^{-1}$.
