Determine the molarity of an antifreeze solution containing 250g water

1.	Determine the molarity of an antifreeze solution containing 250g water mixed with 222g ethylene glycol (C2H6O2). The density of this solution is 1.07g/ml.
Answer» No. of moles of ethylene glycol = n_B Molar mass of C₂H₆O₂ = (24 + 6 + 32)g mol^–1 N_B = 222g/62mol^-1 = 3.58mol mass of solution = (250 + 222)g = 472g

Determine the molarity of an antifreeze solution containing 250g water mixed with 222g ethylene glycol (C2H6O2). The density of this solution is 1.07g/ml.

Answer»

No. of moles of ethylene glycol = n_B

Molar mass of C₂H₆O₂ = (24 + 6 + 32)g mol^–1

N_B = 222g/62mol^-1 = 3.58mol

mass of solution = (250 + 222)g = 472g
