Pure benzene freeze at `5.45^(@)"C"`. A solution containing 7.24g of `"C"_(2)"H"_(2)"Cl_(4)` in 115.3 g of benzene was observed to freeze at `3.55^(@)"C".` What is the molal freezing point constant of benzene?

Pure benzene freezes t 5.3^(@)C . A solution of 0.223 g of phenylacetic acid (C_(6)H_(5)CH_(2)COOH) in 4.4 g of benzene (K_(f) = 5.12 Kkg mol^(-1)) freezes at 4.47^(@)C . From the observation one can conclude that :
