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

(a) `38.71 g`

B

(b) `38.71 mg`

C

(c ) `42 g`

D

(d) `42 mg`

Text Solution

Verified by Experts

The correct Answer is:
A
`:. Delta T = (1000 xx K_(f) xx w)/(m xx W)`
`9.3 = (1000 xx 1.86 xx 50)/(62 xx W)`
`:. W = 161.29`
`:.` Ice separated `= 200-161.29 = 38.71 g`
