Some ethylene glycol `HOCH_(2)CH_(2)OH` is added to your car cooling system along with 5 kg of water .If the freezing point of water glycol solution is `-15.0^(@)C` what is the boiling point of the solution ? `(k_(b)=0.52 kg mol^(-1)` and `k_(f)=1.86 k kg mol^(-1)` for water)

Explanation

`triangleTf=KfxxxM`
`0-(-15)=1.86xxM`
`M=(15)/(1.86)=8.06=4.1912`
`triangleTb=4.1912 Ts-T^(@)A=4.1912+100`
`Ts=104.19^(@)C`
