Q. At a certain temperature, the value of the slope of the plot of osmotic pressure $(\pi)$ against concentration $\left(C\right.$ in $mol\, L ^{-1}$ ) of a certain polymer solution is $291\, R$. The temperature at which osmotic pressure is measured, is $(R$ is gas constant)

Slope, $R T=291\, R$ or $T=291\, K$
$\therefore $ Temperature $=291-273=18^{\circ} C$
