What is the vapor pressure of an ideal solution of ethanol if 1 mile of glycerin is placed in 4 moles of ethanol at 40?C? Pure ethanol has a vapor pressure of 135.3 torr.

Expert Solution

Solution :-

Vapor pressure of solution = mole fraction of solvent * vapore pressure of pure solvent

lets calculate the mole fraction of the ethanol

mole fraction of ethnaol = moles of ethanol / total moles

= 4 mol / (4 mol + 1 mol )

= 0.8

Vapor pressure of solution = mole fraction of solvent * vapore pressure of pure solvent

= 0.8 * 135.3 torr

= 108.24 torr

Therefore vapore pressure of solution = 108.24 torr
