If Kf for water is 1.86gmol−11 , what is the freezing point of 0.1 molal solution of a substance which undergoes no dissociation or association of solute?
The freezing point depression is given as, ΔTf=iKfmΔTf=iKfm Here, i = 0 as there is no dissociation or association of solute. Thus, ΔTf=KfmΔTf=Kfm ΔTf=1.86×0.1=0.186K
