Q. The osmatic pressure of 0.4% urea solution is 1.66 atm. and that of a solutions of sugar of 3.42% is 2.46 atm. When both the solutions are mixed then the osmatic pressure of the resultant solution will be
A) 1.02 atm
B) 2.06 atm
C) 3.04 atm
D) 0.02 atm
Explanation
(b)
$\pi = \frac{1.66 + 2.46}{2} = 2.06\ atm$
