An aqueous solution of `0.1` molal concentration of sucrose should have freezing point `(K_(f)=1.86K mol^(-1)kg)`

A

`0.186^(@)C`

B

`1.86^(@)C`

C

`-1.86^(@)C`

D

`-0.186^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
4
`DeltaT_(f)=K_(f)m=1.86xx0.1=0.186" ",` Freezing point `=0-DeltaT_(f)=-0.186^(@)C`
