Vapor Pressure Lowering (Raoult's Law)
6PRACTICE PROBLEM
At 40.0 °C, the vapor pressures of ethyl acetate and chloroform, which are volatile and nonpolar hydrocarbons, are 188 mmHg and 360 mmHg, respectively. If a mixture of ethyl acetate and chloroform has a vapor pressure of 283 mmHg at 40.0 °C, what is Xchloroform?
