When ' $x$ ' ($\times$10^{-2} $\mathrm{~mL}$) methanol (molar mass (=32 $\mathrm{~g}$); density (=0.792 $\mathrm{~g}$/ \mathrm{cm}^3)) is added to (100 $\mathrm{~mL}$) water (density (=1 $\mathrm{~g}$/ \mathrm{cm}^3)), the following diagram is obtained.
$x=$ ______ (nearest integer). [Given : Molal freezing point depression constant of water at (273.15 $\mathrm{~K}$) is (1.86 $\mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$)]
