A virus is studied by sedimentation equilibrium. The data are:

rotor speed = 800 rpm (remember, w must be in rad/sec)

T = 4°C

v = 0.65 cm3/gm

p = 1.002 gmicm3

rb = 7.30 cm (cell bottom)

ra = 7.00cm (meniscus)

At equilibrium, a graph of In C versus T2 is found to be linear, and Cb/C. = 8.53. What is the molecular weight of the virus?
