Chemistry Question 141 – AP-EAMCET 2026

The value of $K_f{\text{ (in kg mol}}^{-1}\text{)}$ of a solvent (X) is four times the value of its $K_b$. $2g$ of a non-volatile, non-electrolytic solute A is dissolved in $200g$ of solvent X. The $\mathrm{\Delta }{T}_b$ of resultant solution in YK. $4g$ of A is dissolved in $200g$ of X and the $\mathrm{\Delta }{T}_f$ of resultant solution is ZK. What is the ratio of Y and Z? (Molar mass of A=$100{\text{ g mol}}^{-1}$)
