Question

Calculate freezing point depression expected for 0.0711 n aqueous

Answer 1

Answer:

Explanation:

Here m=0.0711m

ΔTf=0.320∘C

Kf=1.86∘Cmol−1

ΔTf=iKfm

i=ΔTfKf×m

=0.3201.86×0.0711

=0.3200.132

=2.4

Answer 2

Explanation:

Depression in freezing point of a solvent upon aaddition of solute is given as: Δ Tf = m.Kf m = molality of the solution = 0.0711 kg/mol Kf = cryoscopic ...
