Osmotic Pressure and van't Hoff Equation

2024 1 question

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