\( 50 \, \text{mL} \) of \( 0.2 \) molal urea solution (density \( = 1.012 \, \text{g mL}^{-1} \) at \( 300 \, \text{K} \)) is mixed with \( 250 \, \text{mL} \) of a solution containing \( 0.06 \, \text{g} \) of urea. Both the solutions were prepared in the same solvent. The osmotic pressure (in Torr) of the resulting solution at \( 300 \, \text{K} \) is ________.
[Use : Molar mass of urea \( = 60 \, \text{g mol}^{-1} \); gas constant, \( R = 62 \, \text{L Torr K}^{-1} \text{ mol}^{-1} \); Assume \( \Delta_{\text{mix}} H = 0 \), \( \Delta_{\text{mix}} V = 0 \)]
