1 litre of a solution containing 500 g of a protein exerts an osmotic pressure of 0.82 atm at `27^(@)C.` The molecular mass of the protein is :

A

82000

B

50000

C

41000

D

15000

Text Solution

Verified by Experts

The correct Answer is:
D
`piV=W_(2)/M_(2) RT,`
`:. 0.82 xx 1 = 500/M_(2) xx 0.0821 xx 300,`
`M_(2) = (500 xx 0.0821 xx 300)/0.82 = 15000`

Molecular mass from osmotic pressure: Pepsin is an enzyme present in the human digestive tract. A solution of a 0.500 gram sample of purified pepsin in 30.0 mL of aqueous solution exhibits an osmotic pressure of 892 torr at 27^(@)C . Estimate the molecular mass of pepsin. Strategy: An enzyme is a protein that acts as a biological catalyst. Pepsin catalyzes the metabolic cleavage of amino acid chain (called peptide chains) in other proteins. To determine molecular mass, we must first find the number of moles (n) of pepsin represented by the 0.500 g sample. We can do this by first rearranging the equation pi=CRT for osmotic pressure to find the molarity of the pepsin solution and then multiplying it by the volume of the solution to obtain the number of moles of pepsin.
