Explain what are the partial pressures of these substances

Reference no: EM13501474

The U.S. Food and Drug Administration lists dichloromethane (CH2Cl2) and carbon tetrachloride (CCl4) 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 1.54 mol of CH2Cl2 and 1.38 mol of CCl4 at 23.5°C? The vapor pressures of pure CH2Cl2 and CCl4 at this temperature are 352 torr and 118 torr, respectively.
