The freezing point of a solution contain...

The freezing point of a solution containing `50 cm^(3)` of ethylene glycol in `50 g` of water is found to be `-34^(@)C`. Assuming ideal behaviour, Calculate the density of ethylene glycol `(K_(f)` for water = `1.86 K kg mol^(-1)`).

Text Solution

Verified by Experts

Given ethylene glycole `=50 cm^(3): k_(1)^(t)= 1.86 K "mol"^(-1) kg`
wt. of glycol `=500xd`, where d is density of glycol
`DeltaT_(t)=(1000xxK_(b)xxW)/(mxxW)`
`34=*1000xx1.86xx50xxd)`/(62xx50)`
`:.d=1.133 g//cm^(3)`
