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^@C`

B

`0.512^@C`

C

`0.86^@C`

D

`0.0512^@C`

Text Solution

Verified by Experts

The correct Answer is:
D
`0.186 = 1.86 xxm , :. M = 0.1`,
`:. DeltaT_b = 0.512 xx 0.1 = 0.0512^@C`
