Chemistry Question on Solutions
The osmotic pressure exerted by a solution prepared by dissolving 2.0 g of protein of molar mass 60 kg mol-1 in 200 mL of water at 27°C is _________ Pa. [Integer value]
(use R = 0.083 L bar mol-1 K-1)
Answer
The correct answer is 415 pa
π = i CRT (i = 1)
π=60×103×2002×1000×.083×300
π = 0.00415 atm
π = 415 Pa
