In a cold climate water gets frozen causing damage to radiator of a car. Ethylene glycol is used as an anifreezing agent. Calculate the amount of ethylene glycol to be added to `4 kg` of water to prevent it from freezing at `-6^(@)` . (`K_(f)` for water = `1.85 kg mol^(-1)`)

Text Solution

Verified by Experts

`DeltaT_(f)=(1000xxK_(f)xxw)/(mxxW)`
Given, `DeltaT_(f)=6^(@), w=?, W=4xx10^(3) gH_(2)O`,
`K_(f)=1.85 K mol^(-1) kg, m_("glycol")=62`
`:. 6=(1000xx1.85xxw)/(4xx10^(3)xx62)`
`:. W_("glycol")=804.32 g`
