Estimate the steady-state concentration profile when a typical albumin solution is subjected to a centrifugal field of 30000 times the force of gravity under the following conditions: the cell length is \(1.0 \mathrm{~cm}\), the molecular weight of albumin is 45000 , the apparent density of albumin in solution is \(1.34 \mathrm{~g} / \mathrm{cm}^{3}\), and the mole fraction of albumin at \(z=0\) (one end of the cell) is \(5 \times 10^{-6}\).
