There is a mixture of two liquids - chloroform and acetone. The vapor pressure of chloroform at 25 °C is 295 torr and that of acetone at the same temperature is 225 torT. a. If the mole fraction of chloroform is 0.30 and that of acetone is 0.70, calculate their vapor pressures and vapor mole fractions (yc and y) considering that this solution is ideal. b. What is an 'ideal' solution? What are the conditions to become an ideal solution and what are the properties of ideal solutions? c. Draw how the vapor pressure curve of acetone, chloroform, and the total solution change as the mole fraction of solution changes.

25 °C is 295 torT and that of acetone at the same temperature is 225 torr.
a. If the mole fraction of chloroform is 0.30 and that of acetone is 0.70, caļculate their vapor pressures and
vapor mole fractions (yc and y) considering that this solution is ideal.
b. What is an 'ideal' solution? What are the conditions to become an ideal solution and what are the
properties of ideal solutions?
c. Draw how the vapor pressure curve of acetone, chloroform, and the total solution change as the mole
fraction of solution changes.
