A spherical protein molecule has a diameter of

0.05\\\\mu m

and a density of

1.18(g)/(c)m^(3)

.\ a. Calculate the molar mass of the protein.\ b. How long will it take for the molecule to diffuse through a distance of

1mm

in water at

20\\\\deg C

.\ c. Neglecting diffusion, calculate the velocity with which the molecule sediments in the earth's gravitational field

(g

)

=

(

9.81(m)/(s^(2)))

.\ d. From your answer in

b

, estimate the time the molecule will take to sediment

1mm

distance.\ e. Suggest a method to increase the velocity of sedimentation.\ f. Suggest an experiment to test whether the protein solution in water is a true one or a colloidal one.
