The following solutions were prepared by dissolving10 gof glucoseC6H12O6in250 mLof waterP1,10 gof ureaCH4N2Oin250 mLof waterP2and10 gof sucroseC12H22O11in250 mLof waterP3.The right option for the decreasing order of osmotic pressure of these solutions is:NEET 2021

Options:

Answer:
A
Solution:

Osmotic pressure (π)=CRT
At same temperature, π∝C

Solution: (1)C1=10180=10180×4

C1=2501000=40180=29

C1=0.222M

Solution: (2) C2=10602501000=16×4=0.667M

Solution: (3) C3=10342×1000250=0.1169M

∵C2>C1>C3∴ Hence, order: P2>P1>P3
