Calculate the cryoscopic constant in `(K Kg mol^(-1))` of cyclohexane. Given that its heat of fusion is `2630J//mol` and it freezing point is `6.6^(@)C`.A. `20.76`B. `28.33`C. `23.15`D. `18.15`

Answer» Correct Answer - A
`K_(f)=(M_("solvent").RT_(f)^(2))/(1000.DeltaH_("Fusion"))`
`=(84xx8.314xx(279.60)^(2))/(1000xx2630)=20.76`
