Chemistry - Liquid Solution Question with Solution | TestHub

Equal volumes of $\frac{\mathrm{M}}{20}\mathrm{NaCl}$ solution and $\frac{\mathrm{M}}{20}$ sucrose solution are mixed. If the osmotic pressure of NaCl, sucrose and the mixture of these solution at same temperature are ${\pi }_1,{\pi }_2$ and ${\pi }_3$, respectively. Calculate $\frac{{\pi }_1+{\pi }_2}{{\pi }_3}$.
