Δ T b = K bm × i =.58 × 2.3 × (.61 / 122/50 / 1000) =0.1334 b.p. =46.2+.1334 =46.334° C

Q. Calculate the boiling point of a solution containing $0.61 g$ of benzoic acid in $50 g$ of carbon disulphide assuming $84%$ dimerization of the acid. The boiling point and $K_{b}$ of $C S_{2}$ are $46. 2^{\circ} C$ and $2.3 K k g m o l^{- 1}$ , respectively.

$Δ T_{b} = K_{b} m \times i$
$= .58 \times 2.3 \times \frac{.61/122}{50/1000}$
$= 0.1334$
$b . p . = 46.2 + .1334$
$= 46.33 4^{\circ} C$
