Depression in F.Pt

Depression in f.p. of an aqueous urea solutio is 1.86^(@) .(K_(f)=1.86^(@) mol^(-1) kg) Hence, mole - fraction of urea in this soluiton is :

Mole fraction of a non-electrolyte in aqueous solution is 0.07 . If K_(f)(H_(2)O) is 1.86^(@) mol^(-1) kg , depression in f.p ., DeltaT_(f) is :
