$200 mL$ of an aqueous solution of a protein contains its $1.26 g$ . The osmotic pressure of this solution at $300 K$ is found to be $2.57 \times 1 0^{- 3}$ bar. The molar mass of protein will beNEET 2011 (Mains)

Options:

Answer:

Solution:

$∵ π = CRT = \frac{w \times 1000}{M \times V ( in mL )} \times RT [∵ C = \frac{n \times 1000}{V ( in mL )} and n = \frac{w}{M}] = \frac{1.26 \times 1000 \times 0.083 \times 300}{2.57 \times 1 0 ^{- 3} \times 200} = 61038 g mol^{- 1}$
