Ethylene glycol is used as an antifreeze...

Ethylene glycol is used as an antifreeze agent. Calculate the amount of ethylene glycol to be added to 4 kg of water to prevent it from freezing at `-6^(@)C.(K_(f)" for "HH_(2)O=1.85" K mol"^(-1)"kg")`

Text Solution

Verified by Experts

Given,
`DeltaT =6^(@)C`,`W_(2)=4 kg = 4000g`,`Mw_(2)=62`,`K_(f)=1.85`
`W_(2) =(Mw_(2)xxW_(1)xxDeltaT)/(1000xxK_(f))`
`(62xx4000xx6)/(1000xx1.85) =804.32 g`.
