One liter of an aqueous urea solution contains 6 g of urea. The osmotic pressure of the solution at 300 K (assuming an ideal behavior) is __________ kPa. (Round off to one decimal place)
[Given: Molecular weight of urea is 60, gas constant (R) is 8.3 J K–1 mol–1]
Correct answer is between '247.0,251.0'. Can you explain this answer?
