200 cm3 of an aqueous solution of a protein contains 1.26 g of the protein.
The osmotic pressure of this solution at 300 K is found to be 2.57 × 10^-3 bar.
Calculate the molar mass of the protein.
Given:
R = 0.083 L bar mol^-1 K^-1
Show Hint
Osmotic pressure is the preferred method for determining the molar mass of macromolecules like proteins because the pressure changes are measurable even at very low molar concentrations.
