Question

The osmotic pressure of a solution at 0C is 4 atm. Its osmotic pressure at 546 K under similar conditions is?
  1. 6
  2. 5
  3. 7
  4. 8


Solution

The correct option is D 8
Let’s look at the following observation.

π1π2=CRT1CRT2

π1π2=T1T2  (Since we have similar conditions except temperature)

4π2=273546  (Plugging in the values)

π2=8 atm
