Place two data sets on the same graph: one for temp vs. x and one for temp vs y (remember, x and y are the mole fractions and they belong on the x-axis). Don’t forget to include the boiling points of the pure substances – they are data, too. Add a trendline (polynomial, 3rd order should work) to each of the coexistence lines separately. Scale the plot appropriately and use the graph to answer the questions. Then complete E5C.1(b)
