Step I: Calculation of molality of the solutionMass of ethylene glycol = 222.6 gMolar mass of ethylene glycol (C2H6O2)= (12×2)+(1×6)+(16×2)= 24+6+32 =62 g mol−1Mass of solution = 200g +222.6 g = 422.6 g = 0.4226kgMolality (m) = Mass of ethylene glycol Molar mass Mass of solvent in kg= (222.6g) (62 g mol−1) 0.4226 kg = 8.49molkg−1Step.
