The solution containing 18 g dm glucose (molar mass 180) in water and another containing 6 g dm of solute A is in water boils at same temperature. What is molar mass of A?

(A)54 g mol
(B)90 g mol
(C)120 g mol
(D)60 g molCorrect

Answer: (D)

Solution

Elevation of boiling point is a colligative property: . Two aqueous solutions of non-electrolytes that boil at the same temperature have the same , hence the same molality; for dilute aqueous solutions this means the same molar concentration (same number
