A solution is prepared by dissolving \( 0.3 \, \text{g} \) of a non-volatile non-electrolyte solute 'A' of molar mass \( 60 \, \text{g mol}^{-1} \) and \( 0.9 \, \text{g} \) of a non-volatile non-electrolyte solute 'B' of molar mass \( 180 \, \text{g mol}^{-1} \) in \( 100 \, \text{mL} \) \( \mathrm{H_2O} \) at \( 27^{\circ}\mathrm{C} \). Osmotic pressure of the solution will be \( [\text{Given: } R = 0.082 \, \mathrm{L\, atm\, K^{-1}\, mol^{-1}}] \)
