Question

ethylene glycol is used as antifreeze in a cold climate. mass of ethylene glycol which should be added

Answer 1

Ethane-1,2-diol, (ethylene glycol, monoethylene glycol, MEG) which is manufactured from ethene via epoxyethane, is used to make polyester fibres, resins and films although it is probably better known for its use as a coolant in cars. It is miscible with water and it lowers the freezing point of water so it is used as an antifreeze.
