A spherical piece of candy is suspended in flowing water. The candy has a density of 1950 kg/m³ and has a 1.0 cm diameter. The water velocity is 1.0 m/s, the water density is assumed to be 1000.0 kg/m3, and the water viscosity is 1.0x10⁻³ kg/m/s. The diffusion coefficient of the candy solute in water is 2.0x10⁻⁹ m²/s, and the solubility of the candy solute in water is 2.0 kg/m³. Calculate the mass transfer coefficient (m/s) and the dissolution rate (kg/s).
