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