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) |
Answer» `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` |
