The U.S. Food and Drug Administration lists dichloromethane (CH,CI,) and carbon tetrachloride (CCI4) among the many chlorinated organic compounds that are carcinogenic (cancer-causing). What are the partial pressures of these substances in the vapor above a solution of 1.74 mol of CH2CI2 and 1.17 mol of CCI4 at 23.5C? The vapor pressures of pure CH2CI, and CCI4 at this temperature are 352 torr and 118 torr, respectively. (Assume ideal behavior.) PCH2C12 torr PcClA torr
