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 ∘^\circ C is ______________ Pa. [integer value]

(use R = 0.083 L bar mol −- 1 K −- 1)

Step-by-Step Verified Solution

π=iCRT(i=1)\pi=\mathrm{i} C R T \quad(\mathrm{i}=1)

π=2×100060×103×200×.083×300\pi=\frac{2 \times 1000}{60 \times 10^{3} \times 200} \times .083 \times 300

π=0.00415 atm\pi=0.00415 \mathrm{~atm}

π=415 Pa\pi=415 \mathrm{~Pa}
