Chlorobenzene, C6H5Cl, is used in the production of many important chemicals, such as aspirin, dyes, and disinfectants. One industrial method of preparing chlorobenzene is to react benzene, C6H6, with chlorine, as represented by the following equation. C6H6(l) + Cl2(g) ⎯→ C6H5Cl(l) + HCl(g) Find the number of moles of chlorine used if 3.8 moles of Chlorobenzene gas are generated in the reaction
