The freezing point of a `5g CH_(3)COOH (aq) ` per `100g` water is `01.576^(@)C`. The van't Hoff factor `(K_(f)` of water `-1.86K mol^(-1)kg) :`

A

`0.996`

B

2

C

`0.5`

D

`1.016`

Text Solution

Verified by Experts

The correct Answer is:
4

`DeltaT_(f)=K_(f)mxxi`
`1.576=(5xx1000xx1.86xxi)/(60xx100)`
`i=1.016`
