Solution
The correct option is D8atm Osmotic pressure (π) is given by π=CRT
where C is the concentration (molarity)R is ideal gas constantT is temperature
Condition 1:
When temperature is 0∘C=273K π1=C×R×273..eq(i)
Condition 2:
When temperature is 546K π2=C×R×546..eq(ii)
Dividing both the equations:
