The plot of osmotic pressure

(\Pi)

vs concentration (

\mathrm{L}^{\text{bar mol-1}

}

. The temperature at which the osmotic pressure measurement is done is

D. $37^{\circ} \mathrm{C}$

\Pi=\text{ CRT } Slope = RT

\begin{aligned} & 25.73=0.083 \times \mathrm{T} \\ & \mathrm{T}=\frac{25.73}{0.083}=309.47 \approx 310 \mathrm{ K} \end{aligned}

\therefore
