A solution concentration is expressed in molarity and not in molality while considering osmotic pressure. Why?

Give Reason: Concentration is expressed in molality and not molarity?

While considering boiling point elevation and freezing point depression of a solution concentration is expressed in molality and not in molarity. Why?

How is molar mass of a solute determined by osmotic pressure measurement?

Which of the following solution has highest osmotic pressure ?
