A bubble of pure chlorine gas 0.5 cm in diameter and at 1.0 atm is rising at a velocity of 20 emfs in pure water at 16°C. Chlorine from the bubble surface is dissolved in water and diffuses away, making the bubble smaller. The maximum amount of chlorine that can dissolve in water (saturation solubility) at this temperature, which is also the concentration at the surface of the bubble, is 0.823 g of chlorine per 100 g of water. The diffusivity of chlorine gas in water at this temperature is 1.26 x 10- 9 m2 / s. The density and viscosity of water are 1000 kg/ m3 and 1.155 x 10- 3 kg/ m·s, respectively. What is the rate (in grams per second) of absorption of the bubble by the water when the bubble is 0.5 cm in diameter?
