A liquid mixture of a certain mole fraction of ethanol and a certain mole fraction of methanol was placed in an evacuated (i. e., no air) bottle and after many days is now in equilibrium with its vapor. Assuming Raoult's Law applies (actually, both activity coefficients are within 0.02 of unity), and that the mole fractions in the vapor at 25°C are yE = 0.166, and yM = 0.834. What is the mole fraction of each compound in the liquid at 25°C? (Note: E = Ethanol, M = Methanol)

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

the correct answer to this question is 2
