Q 1210880719.     `1.22` g `C_6H_5COOH` is added into two solvents and data of `ΔT_b` and `k_b` are given as:

(i), In `100` g `CH_3COCH_3, ΔT_b = 0.17`

`k_b = 1.7` K kg/mol

(ii), In `100 g` benzene, `ΔT_b = 0.13` and

`k_b = 2.6` K kg/mol

Find out the molecular weight of `C_6H_5COOH` in both the cases.
