Calculate the amount of ice that will separate out on cooling containing `50 g `of ethylene glycol in `200 g` of water to `-9.3^(@)C (K_(f)` for water =`1.86 K mol^(-1) kg`)

A

38.71 g

B

38.71 g

C

42 g

D

42 g

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaT=(1000xxK_fxxw)/(WxxM) rArr 9.3 =(1000xx1.86xx50)/(62xxw)rArr therefore W=161.29`
`therefore` Ice separated = 200-161.29 =38.71 g
