Question

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, _ mix H = 0, _ mix V = 0]
