The amount of ice that will separate out...

The amount of ice that will separate out on cooling a solution containing `60g` of ethylene glycol in `200g` water to `-9.3^(@)C` is: (`K_(f)'=1.86K "molality"^(-1)`)

A

177.78 g

B

129.03 g

C

222.22 g

D

270.97 g

Text Solution

Verified by Experts

The correct Answer is:
D
`Delta T_(f)=9.3`
`(40)/(62)xx(1000)/((400-x))xx1.86=9.3`
`(40xx1000)/(62xx9.3)xx1.86=400-X`
`x=400-129.03`
x=270.97
