12.2 g of benzoic acid is dissolved in (...

`12.2 g` of benzoic acid is dissolved in (i) `1 kg` acetone `(K_(b) = 1.9 K kg mol^(-1))` and (ii) 1 kg benzene `(K_(b) = 2.6 K kg mol^(-1)`.
The elevation of boiling points are `0.19^(@)C` and `0.13^(@) C`, respectively.
a. What are the molar masses of benzoic acid in the two solutions ?
, b. What are the structures of benzoic acid in the two solutions ?

AI Generated Solution

To solve the problem, we need to find the molar masses of benzoic acid in two different solutions (acetone and benzene) using the elevation of boiling point data provided. ### Step-by-Step Solution: **Given Data:** - Mass of benzoic acid (solute) = 12.2 g - Mass of solvent (acetone or benzene) = 1 kg = 1000 g - Elevation of boiling point in acetone (ΔT_b1) = 0.19 °C ...
