The diffusion constant for the amino acid glycine in water is 1.06 × 109 m²/s. In a 2.0-cm-long tube with a cross-sectional area of 1.8 10-4 m², the mass rate of diffusion is m/t = 4.2 x 10-14 kg/s, because the glycine concentration is maintained at a value of 8.7 x 10-3 kg/m³ at one end of the tube and at a lower value at the other end. What is the lower concentration?
