Find the mass of glycol required to run a car at a hill station having having temperature -10 degre celcius and radiator of car can accomadate 5L of liquid. Kf for water is 1.86 K kg per mol and molar mass of glycol is 62 gper mol Share with your friends Share 0 Raveena Sharma answered this The solution is as follows: ∆T = Kf . m m = ∆TKf= 101.86=5.38 m = number of moles of solutemass of solvent in g×1005.38 = n5 ×1000 (density of water is 1)5.38 = wM×5×1000 (M = 62 g/mol) w = 0.86 g 2 View Full Answer
