groundwater. Chlorobenzene is a common solvent as well as an intermediate in chemical manufacturing. Chlorobenzene (C6H5Cl), a contaminate in ground water, is diffusing into an inert porous mineral particle at 25C. The porous particle has a void fraction of 0.25 with a mean pore diameter of 0.10m, and the pores are filled with groundwater. The mass concentration of chlorobenzene in the groundwater surrounding the particle is 0.050g/L, which is below its solubility limit. b. What are the mole and mass fractions of chlorobenzene in the groundwater? c. Estimate the molecular volume of a chlorobenzene molecule
