200 cm^3 of aqueous solution ofa 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) |
| Answer» SOLUTION :`pi`V = nRT, MOLARMASS,`M_B = (W_BRT)/(pi V) = (1.26xx0.083xx300)/(0.2xx8.3xx10^(-2)` = 1890g`mol^(-1)` | |
