Ethylene glycol is used as an antifreeze in a cold climate. Mass of ethylene glycol which should be added to 4 kg of water to prevent it from freezing at - 6^(@)C will be ( K for water = 1.86 "K kg mol"^(-1), and molar mass of ethylene glycol = 62 g "mol"^(-1) ) |

Answer» 400.00 g `6=(1.86xx1000xxw_(2))/(4000xx62)` `w_(2)=(6xx4000xx62)/(1.86xx1000)=800G` |
