							0.9% of  aqueous solution  of solute means 0.9 gram of solute X present in 100 gram of solution.  It means given weight of solute is 0.9 gram.  Formula of osmotic pressure isPi = n/v RT.  Put the value of n= 0.9/60(given weight of solute /molar mass of solute) ,v=100, R= 0.0820 and find the answer. OK
