NEET 2021 Chemistry question
The following solutions were prepared by dissolving 10 g of glucose () in 250 ml of water (P), 10 g of urea () in 250 ml of water (P) and 10 g of sucrose () in 250 ml of water (P). The right option for the decreasing order of osmotic pressure of these solutions is :
Answer: (A)
Solution
Equal masses: smaller molar mass means higher molarity and higher : urea > glucose > sucrose.
