The osmotic pressure of 0.4% urea solution is 1.66 atm and that of a solution of sugar of 3.42% is 2.46 atm. When equal volumes of both the solutions are mixed then the osmotic pressure of the resultant solution will be?

Options:

Answer:

Solution:

$π_{f} = [\frac{c_{1}}{2} + \frac{c_{2}}{2}] RT$

As volume is doubled, concentration is halved

$∴ π_{f} = \frac{c_{1} RT + c_{2} RT}{2}$

$\frac{π_{1} + π_{2}}{2} = \frac{1 .66 + 2 .46}{2}$

$= 2.06$ atm.
