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?
