The vapour pressure of an aqueous solution of cane sugar (mol. Mass = 342) is 732 mm at 100^(@)C. Calculate the boiling point of the solution (K_(b) for water =0.52^(@)C).

Answer»


SOLUTION :`p_(0)=760MM, p_(s)=732mm." First apply "(p_(0)-p_(s))/(p_(0))=(n_(2))/(n_(1))=(n_(2))/(1000//81)""("taking "w_(1)=1000g)`
`n_(2)="MOLALITY (m)"`
`"Apply"DeltaT_(b)=K_(b)xxm`.
