We have to determine whether the given solution of methanol and water is ideal or not.
An ideal solution is the one which the gas phase exhibits the properties identical to those of ideal gases.
The vapor pressure of each component of an ideal solution follows the Raoult’s law.
A solution of methanol and water has a mole fraction of water of 0.312 and a total vapor pressure of 211 torr at 39.9oC. The vapor pressures of pure methanol and pure water at this temperature are 256 torr and 55.3 torr, respectively.
Is the solution ideal?
