`A 0.50` molal solution of ethylene glycol in water is used as coolant in a car. If the freezing point constant of water is `1.86^(@)` per molal, at which temperature will the mixture freeze?

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaT_(f)=k_(f)m`.
`DeltaT_(f)=1.86xx0.5=0.93`.
so `T_(f)=-0.93^(@)C`.
