A spherical protein molecule has a molar mass of 60,230 g/mol and a density of 1350 kg/ m3. What will its terminal velocity be in water of viscosity 1.0x10-3N/m2 s? How long will it take to fall 1 cm?

The time is very long and can be shortened by placing the material in a centrifuge where a very large artificial g can be created.

HINT: Find the mass of a single molecule. Find the volume of a single molecule. Use the volume to find the radius.
