1.	Water is used in car radiators. In winter season, ethylene glycol is added to water so that water may not freeze. Assuming ethylene glycol to be non-volatile, calculate the minimum amount of ethylene glycol to be non-volatile, calculate the minimum amount of ethylene glycol that must be added to 6.0 kg of waterof prevent it from freezing at -0.30^(@)C. The molar depression constant of water is 1.86 K//m.
Answer» Solution :`w_(1)=6000g, DeltaT_(f)=0.30^(@),K_(f)=1.86^(@)C` `"Molar mass of ethylene glycol,"{:(CH_(2)OH),("\|"),(CH_(2)OH):}(M_(2))="62 g mol"^(-1)` `"SUBSTITUTE in the formula, M"_(2)=(1000K_(f)w_(2))/(w_(1)DeltaT_(f))." Calculate w"_(2)`.
