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 form freezing at - 6° C will be : (K_f for water = 1.86 K kg mol^-1, and molar mass of ethylene glycol = 62g mol^-1)

804.32 g

204.30 g

400.00 g

304.60 g

Solution

804.32 g

ΔT_f = iK_fm
ΔT_f = 6ºC
w1 = mass of ethylene glycol in grams
w2 = mass of solvent (H₂O) in grams= 4000g
m1 = Molar mass of ethylene glycol = 62 g
i = 1
i is van't off factor
