Question

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