2. Solving a chemistry problem

7. Acetone and ethyl ether are infinitely soluble in each other. At 20 °C, the partial pressures of these substances over their mixtures of various compositions, expressed in mole %, are given in the table:
χ of acetone,% 0
5.20
24.90 45.7 61.2 66.6 84.2 97.9 99.9 100
raceton, mm. rt. Art. 0 20 70 105 127 135 160 181 184 185
refira, mm. rt. st 444 422 350 282 224 199 111 15 2 0
According to the table, plot the curves of the partial pressures of acetone and ether vapors and the total vapor pressure on the composition of the mixture. Is this blend perfect? Using the diagram, determine: a) partial and total vapor pressure for an equimolecular mixture of acetone and ether; b) the composition of the mixture that will boil at 290 mm. rt. Art.
