The vapor pressure of dichloromethane CH2Cl2 at 0`C in 134 mm Hg . The normal boiling point of dichloromethane is 40 `C . Calculate its molar heat of vapourization

  1. how did you obtain P2

  2. at normal boiling point vapor pressure is always equal to atmospheric pressure.hence atmospheric pressure = 1 atm = 760 mm Hg .

  3. How did you get those units from 8.3145 J/(mol*K)?? mol and mmHg dont cancel out do they?

    1. Those units just come standard with the R constant.I Both pressures cancel each other out and I am not exactly sure about the mole

  4. Can u please make a clarification about units cancel?
