MHT CET Chemistry question
The osmotic pressure of 0.4% urea solution is 1.66 atm and that of solution of sugar of 3.42 % is 2.46 atm. When both the solution are mixed then the osmotic pressure of the resultant solution will be
Answer: (C)
Solution
On mixing equal volumes the total solute concentration (and hence osmotic pressure) is the mean of the two:
