`200 cm^3` of aqueous solution of a protein contain 1.26g of protein. The osmotic pressure of solution at 300K is found to be `8.3xx10^(-2)`bar. Calculate the molar mass of protein, (R=0.083 l bar `K^(-1)mol^(-1)`

Text Solution

Verified by Experts

`pi`V = nRT, molarmass,`M_B = (W_BRT)/(pi V) = (1.26xx0.083xx300)/(0.2xx8.3xx10^(-2)` = 1890g`mol^(-1)`
