`1.22 g` of benzoic acid is dissolved in acetone and benzene separately. Boiling point of mixture with acetone increase by `0.17^(@)C` and boiling point of mixture with benzene increases by `0.13^(@)C`.   `K_(b) ("acetone")=1.7 K kg "mol"^(-1)`,   Mass of acetone `= 100 g`,   `K_(b) ("benzene")=2.6 k Kg mol^(-1)`,   Mass of benzene `= 100 g`,   Find molecular weight of benzoic acid in acetone and in benzene solution. Justify your answer with structure.
