The relative decrease in `VP` of an aqueous glucose dilute solution is found to be `0.018`. Hence, the elevation in boiling point is (it is given `1 molal` aqueous urea solution boils at `100.54^@)C` at `1 atm` pressure)

Options

A. `0.018^(@)C`
B. `0.18^(@)`
C. `0.54^(@)`
D. `0.03^(@)`

Explanation

`x_(B)=(DeltaP)/(p_(A)^(@))=0.018" " , " " DeltaT_(b)=K_(b).mimplies0.54=K_(b)xx1impliesK_(b)=0.54`
`m=(chi_(B))/(1-chi_(B))xx1000/(M_(A)) " "m=0.018/0.982xx1000/18impliesDeltaT_(b)=K_(b)xxm=0.54^(@)C`
