4. Ethylene glycol (C2H6O2) is used as an antifreeze in cars. If 400 g of ethylene glycol is added to 4.00 kg of water, what is the molality? Calculate how much the freezing point of water will be lowered. The freezing-point depression constant for water is Kf = –1.86°C/m. Show your work. molality = 400/(62x4)=1.61m delta Tf = Kf x m = -1.81 x 1.61 = -2.99 C @Somy
