Consider a spherical cell of radius 8 micrometers. The cell is suddenly placed in a solution of pure water. For simplicity, assume that the cell is a 0.15 M NaCl solution and the fluid density inside the cell is 1.005 g/ml. The density of pure water is 1g/ml.
a) Explain why the cell swells.
b) What is the concentration difference of water between inside and outside the cell.
