The plot of osmotic pressure (П) vs concentration $$(\mathrm{mol} \mathrm{~L}^{-1})$$ for a solution gives a straight line with slope $$25.73 \mathrm{~L} \mathrm{~bar} \mathrm{~mol}^{-1}$$. The temperature at which the osmotic pressure measurement is done is
(Use $$\mathrm{R}=0.083 \mathrm{~L} \mathrm{~bar} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$$)
Identify the correct answer.
