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 `CS_(2)` are `46.2^(@)C` and `2.3 kg mol^(-1)`.

Answer

`46.33^(@)"C"`

Explanation

`Delta"T"_("b")=[1+((1)/("n")-1)alpha]"K"_("b")("w"_("solute")xx1000)/("m"_("solute")xx"w"_("solvnet"))`
`=[1+((1)/("2")-1)xx0.84]xx(2.3xx.061xx1000)/(22xx50)`
`=0.13^(@)"C"`
`"T"_("b")("solution")=46.2+0.13=46.33^(@)"C"`
