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 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; R = 62 L Torr K⁻¹ mol⁻¹; assume ΔmixH = 0 and ΔmixV = 0.]
