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, `Delta_(max)H=0 , Delta_(mix)V=0]`
