1.	Mark the correct option for the `K_(f)` . I. `K_(f) `depends on nature of solvent. II. `K_(f)` is also known as freezing point depression constant or molal depression constant. III. `K_(f)` is known as cryoscopic constant. IV. `"Unit of "K_(f)=Kkg" mol"^(-1)`. V. `M_(2)=(K_(f)xxW_(1)xx1000)/(DeltaT_(f)xxW_(2))`. where`W-(2)` is the mass of solute haveing molar mass of `M_(2)` present in `W_(1)` gram of solvent.A. I, II and IIIB. I, II, III and IVC. I. II, III, IV and VD. II, III, IV and V
Answer» Correct Answer - B (V) option is wrong correct formula : `M_(2)=(K_(f)xxw_(2)xx1000)/(DeltaT_(f)xxw_(1))`
