As we learned 

 

Osmotic Pressure -

Osmotic Pressure  (\pi) is excess pressure developed on solution side due to osmosis.

-

 

 P=\frac{w}{mv}Rt   since wvT are constant thus

 P\propto \frac{1}{m};\: P_{2}> P_{1}> P_{3}

 


Option 1)

P_{1}> P_{2}> P_{3}

 

 

 

Option 2)

P_{3}> P_{1}> P_{2}

Option 3)

P_{2}> P_{1}> P_{3}

Option 4)

P_{2}> P_{3}> P_{1}
