When `1.22 g C_(6)H_(5)COOH` is added into two solvents, the following data of `DeltaT_(b)` and `K_(b)` are obtained:
i. In `100 g CH_(3)COCH_(3)`,`DeltaT_(b)=0.17`,`K_(b)=1.7 kg K mol^(-1)`.
ii. In `100 g` benzene,`DeltaT_(b)=0.13` and `K_(b)=2.6 kg K mol^(-1)`.
Find out the molecular weight of `C_(6)H_(5)COOH` in both cases and interpret the results.
