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?

The chlorine content of a pool with a capacity of 1.80×104 L was discovered to be 0.00145% by mass, which is well below the sanitary level of 0.00305%. How much chlorine needs to be added in order for the pool to meet the health regulation standard of 0.00305%? First draw a flowchart, then given that the pool consists of fresh water and chlorine, write the total mass (or alternatively chlorine mass) and fresh water balance equations, and then calculate the mass of chlorine in grams that needs to be added to the pool. Assume that the density of the pool water is the same as that of fresh water (1.00 kg/L), the pool is filled to its rated capacity (1.80×104 L), and that the required chlorine can be added to this capacity.
