Radius ratio Radon

Radon (M = 0.222 kg/mole) is placed in a centrifuge s rotor with radius / = 0.2 m at temperature T = 300 K. Determine the ratio of concentration n R)ln 0)) of radon atoms near the rotor s walls to that on the centrifuge axis if frequency of the rotor rotation is equal to n = 12X10 min ...
