Can I plot a phase diagram (P against T) of a mixture if the mole compositions are known?

Is it possible? Or do I have to actually experiment it in a lab? If it's possible, what data would I need? I'm right now only given the mole percentages and the weight percentages. I do know I can ...

Phase diagram binary mixture

The Gibbs Phase Rule states: F = C - P + 2. From this it is possible to construct a phase diagram. In case of a 1-component system C=1 and where P denotes the number of phases in equilibrium. In case ...

Constant Pressure lines in evaporation diagram

Assume that there is the following $T-H$ phase diagram with the constant pressure lines. Which is greater preasure? The preasure drops as we move to lower temperatures (i.e. from top to bottom)? ...
