The freezing point depression constant (Kf) of benzene is 5.12 K kg mo

1.	The freezing point depression constant (Kf) of benzene is 5.12 K kg mol–1. The freezing point depression for the solution of molality 0.078 m containing a non-electrolyte solute in benzene is (rounded off upto two decimal places) : (1) 0.60 K (2) 0.20 K (3) 0.80 K (4) 0.40 K
Answer» (4) 0.40K ΔT_f = K_f × m = 5.12 × 0.078 ΔT_f= 0.40 K

Answer»

(4) 0.40K

ΔT_f = K_f × m

= 5.12 × 0.078

ΔT_f= 0.40 K
