Solutions

At \(27^{\circ} \mathrm{C}\), a solution containing \(2.5 \mathrm{~g}\) of solute in \(250.0 \mathrm{~mL}\) of solution exerts an osmotic pressure of \(400 \mathrm{~Pa}\). The molar mass of the solute is ___________ \(\mathrm{g} \mathrm{~mol}^{-1}\) (Nearest integer)

(Given : \(\mathrm{R}=0.083 \mathrm{~L} \mathrm{~bar} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}\))
