A solution having 54 g of glucose per litre has an osmotic pressure of 4.56 bar. If the osmotic pressure of a urea solution is 1.52 bar at the same temperature, what would be its concentration?

Question

Correct answer: D. Concentration of glucose solution = 54 g/L / 180 g/mol = 0.3 M. Since π = C * R * T, for two solutions at the same temperature: π_1 / π_2 = C_1 / C_2 => 4.56 / 1.52 = 0.3 / C_urea => 3.0 = 0.3 / C_urea => C_urea = 0.1 M.
