What is the osmotic pressure of a 100 ml of toluene solution that contains a total of 0.005 moles of a polymer dissolved in it at 25°c? give your answer in atm?

Osmotic pressure is the pressure that would have to be applied to a pure solvent to prevent it from passing into a given solution by osmosis.

That can be mathematical computed from the expression:

Osmotic pressure=C*R*T

Where,

C = Concentration

R=Gas constant

T=Temperature

Concentration=Number of moles of solute/Volume (L)

=0.005*1000/100

=0.05

R = 0.08206 atm L/mol K

T=25+273

=298

Osmotic pressure = 0.05*0.08206*298

=1.2 atm
