The freezing point of a `0.05` molal solution of a non-electrolyte in water is:
(`K_(f) = 1.86 "molality"^(-1)`)

A

`-1.86^(@)C`

B

`-0.93^(@)C`

C

`-0.093^(@)C`

D

`0.093^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
C

`DeltaT_(f)=1.86 xx 0.05 = 0.093`,
`:.T_(f)=0-0.093 =-0.093^(@)C`
