An aqueous solution freezes at
`-0.186^(@)C (K_(f)=1.86^(@)` ,`K_(b)=0.512^(@)`. What is the elevation in boiling point?

A

0.186

B

0.512

C

`(0.512)/(1.86)`

D

0.0512

Text Solution

Verified by Experts

The correct Answer is:
D
`DeltaT=K_(f)xxm`
`0.186=1.86xxm`
`m=0.1`
`DeltaT=K_(b)xxm=0.512xx0.1 =0.0512`]
