The vapor pressure of dichloromethane, c h 2 c l 2 , at 0 ∘ c is 134 mmhg . the normal boiling point of dichloromethane is 40. ∘ c. calculate its molar heat of vaporization.

 the vapor pressure of the liquid at a temperature T2 ... Now, it's important to realize that the normal boiling point of a substance is measured at an atmoshperic ... ΔHvap=−ln(134mmHg760mmHg )⋅8.314J mol−1K−1 (1(273.15+0)−1(273.15+40))K−1 ... Give equations that can be used tocalculate the .

Now try it yourself :)

You know how the first one if filled up like the objects do the same but with the other categories
