Osmotic pressure

Read the following statements . The correct symbols filling the blanks A and B are Osmotic pressure of a concentrated solution .............A..........osmotic pressure of a dilute solution . Diffusion pressure deficit of a concentrated solution ..........B...... diffusion pressure deficit of a dilute solution

2.5 g of a substance is present in 200 mL of solution showing the osmotic pressure of 60 cm Hg at 15^(@)C . Calculate the molecular weight of substance.What will be the osmotic pressure if temperature is raised to 25^(@)C ?

Solute A is a ternary electrolyte and solute B is non-elctrolyte . If 0.1 M solution of solute B produces an osmotic pressure of 2P ,then 0.05M solution of A at the same temperature will produce on osmotic pressure equal to
