JEE Main 2019 Chemistry question
The osmotic pressure of a dilute solution of an ionic compound XY in water is four times that of a solution of 0.01 M BaCl in water. Assuming complete dissociation of the given ionic compounds in water, the concentration of XY (in mol L) in solution is:
Answer: (D)
Solution
2c = 4 × 3 × 0.01 ⇒ c = 0.06 M.
