An antifreeze solution is prepared for a laboratory experiment. In this solution 222.6g of ethylene glycol is dissolved in 200g of water. The density of resultant solution was found to be 1.072 "g mL"^(-1). Molal depression constant of water is "1.86 K kg mol"^(-1) and molar mass of ethylene glycol (C_(2)H_(6)O_(2)) is "62 g mol"^(-1). Molality of solution is : |
