Calculate the osmotic pressure of an aqueous solution containing $1\mathrm{g}$ each of sucrose and glucose per ${\mathrm{dm}}^3$ at $300 \mathrm{K}.$ If this pressure was measured and it were not known that the solute was a mixture, what molecular weight would be expected?

Calculate the concentration of that solution of sugar which has osmotic pressure $2.46$ atmosphere at $27°\mathrm{C}.$

A $4$ percent solution of sucrose $\left({\mathrm{C}}_{12}{\mathrm{H}}_{22}{\mathrm{O}}_{11}\right)$ is isotonic with $3$ percent solution of an unknown organic substance. Calculate the molecular weight of the unknown substance.

The given aqueous solution of a protein contains $1.26 \mathrm{g}$ of the protein in $200{ \mathrm{cm}}^3$ solution. The osmotic pressure of this solution at $300 \mathrm{K}$ is found to be $2.57\times {10}^{-3} \mathrm{bar}.$ Calculate the molar mass of the protein.
