    If the osmotic pressure of a 0.010 M aqueous solution of sucrose at 27°C is 0.25 atm, then the osmotic pressure of a 0.010 M aqueous solution. of NaCl at 27°C is

    A) 0.062 atm           

    B)  0.12 atm

    C)  0.25 atm             

    D) 0.50 atm                

    Correct Answer: D

    Solution :

    Osmotic pressure =i CRT, For both the solutions, .all other conditions are similar except ?i' which is 1.0 for sucrose while 2.0 for NaCI. Therefore, osmotic pressure of NaCI = 2 x 0.25 = 0.50 atm
