Explanation / Answer

A. Frictional force (f) = kT/D

k = Boltzmann constant = 1.38*10^-16 g cm2/s2

T = 20C = 293K

D = diffusion coefficient = 11.2*10^-11 m2/s = 11.2*10^-7 cm2/s

f = 1.38*10^-16 * 273/ 11.2*10^-7 = 33.6375 * 10^-9 g/s = 33.6375 * 10-12 kg/s

f = 33.6375 * 10-12 kg/s

B. f/fo = 1.21

fo = f/1.21 = 33.6375 * 10-12 kg/s/1.21

fo = 27.8 * 10-12 kg/s
