`300cm^(3)` of an aqueous solution of a protein contains 2.12 g of the protein, the protein, osmotic pressure of such a solution at 300 K is found to be `3.89xx10^(-3)" bar."` Calculate the molar mass of the protein. `("R = 0.0823 L bar mol"^(-1)K^(-1))`

Text Solution

Verified by Experts

`V = 300cm^3`= 0.300 litre
T= 300k, `pi=3.89 xx 10^-2`bar
R= 0.0823 L bar `mol^-1 K^-1. w_2= 2.12g`
`M_2 WRT//piv = ((2.12)xx (0.0823)xx(300))/(3.89xx10^-3xx0.3)`
`M_2= 44852.4 `g/mol
