In an experiment, a sphere of crystalline sodium chloride (NaCl) was suspended in a stirred tank filled with water at 20°C. Its initial mass was 100 g. In 10 minutes, the mass of the sphere was found to have decreased by 10 percent. The density of NaCl is 2160 kg/m3. Its solubility in water at 20°C is 320 kg/m3. Use these results to obatin an average value for the mass transfer coefficient.
