question_answer 66)

  At a given temperature, osmotic pressure of a concentrated solution of a substance.......... (a) is higher than that of a dilute solution (b) is lower than that of a dilute solution (c) is same as that of a dilute solution (d) cannot be compared with osmotic pressure of dilute solution

Answer:

                  (a) According to definition of osmotic pressure we know that n = CRT. For concentrated solution C has higher value than dilute solution. Hence, as concentration of solution increases osmotic pressure will also increase.
