A solution of protein (extracted from crabs) was prepared by dissolving 0.75 g in 125 cm^(3) of an aqueous solution. At 4^(@)C,an osmotic pressure rise of 2.6 mm of the solution was observed. Thenmolecular weight of protein is (Assume density of solution is 1.00 g//cm^(3))

Answer»

`9.xx10^(5)`
`5.4xx10^(5)`
`5.4xx10^(10)`
`9.4xx10^(10)`

Solution :Given h = 2.4 mm = 0.26 CM, V = 125 `cm^(3)`
