प्र: 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: (Kf for water = 1.86 Kg/mol and molar mass of ethylene glycol = 62 kg/mol) 1411 0

उत्तर : 3. "804.32 g"
व्याख्या :
Answer: C) 804.32 g Explanation: ∆Tf = kf.m for ethylene glycol in aq. solution ∆Tf = kf wmol.wt × 1000wt. of solvent6 = 1.86 x w x 100062 x 4000 => w = 800 g So, the weight of solute should be more than 800 g.
