Question

What is the freezing point depression constant of a solvent, 50 g of which contain 1 g non volatile solute (molar mass $256\;{\rm{g}}\;{\rm{mo}}{{\rm{l}}^{-1}}$) and the decrease in freezing point is 0.40 K ?

Select the correct option:

$3.72\;{\rm{K}}\;{\rm{kg}}\;{\rm{mo}}{{\rm{l}}^{ - 1}}$

$4.43\;{\rm{K}}\;{\rm{kg}}\;{\rm{mo}}{{\rm{l}}^{ - 1}}$

$1.86\;{\rm{K}}\;{\rm{kg}}\;{\rm{mo}}{{\rm{l}}^{ - 1}}$

$5.12\;{\rm{K}}\;{\rm{kg}}\;{\rm{mo}}{{\rm{l}}^{ - 1}}$
