Osmotic Pressure Proportional to Concentration Difference

What is the osmotic pressure of a solution prepared by adding 13.65 grams of sucrose (C12H22O11) to enough water to make 250 mL solution at 25 C.

The formula of osmotic pressure is: Π = iMRT where i is the van't Hoff factor of the solute, M is the molar concentration, R is the universal gas constant and T is the temperature in Kelvins.
