The U.S. FDA lists dichloromethane (CH2Cl2) and carbon
tetrachloride (CCl4) (both volatile substances) among many cancer-
causing chlorinated organic compounds. What is the total vapor
pressure of a solution that consists of 1.60 mol CH2Cl2 and 1.10
mol of CCl4 at 23.5°C? The vapor pressures of pure CH2Cl2 and
CCl4 at 23.5°C are 352 Torr and 118 Torr, respectively. (Assume
ideal behavior).
