The vapor pressure of methyl alcohol is 254 mm Hg at 40oC and at the same temperature the vapor pressure of ethyl alcohol is 135 mm Hg. Solutions of the two alcohols behave ideally; that is, they follow Raoult's law. Determine the vapor pressure at 40oC of a solution made by mixing 2.00 moles of methyl alcohol with 1.00 moles of ethyl alcohol?
