A certain mass of a substance when dissolved in 100 g $C_6H_6$ lowers the freezing point by 1.28$^{\large\circ}$C. The same mass of solute dissolved in 100 g of water lowers the freezing point by 1.40 $^{\large\circ}$C. If the substance has normal molecular weight in benzene and is completely dissociated in water, into how many ions does it dissociate in water? $K_f$ of $H_2O$ and $C_6H_6$ are 1.86 and 5.12 K $mol^{-1 }$ respectively.
