What is the mole fraction of ethanol in the vapor phase over an ethanolmethanol solution that has a mole fraction of ethanol of 0.30 in the liquid phase? The vapor pressures of pure ethanol and pure methanol are 44 Torr and 94 Torr, respectively at this temperature.

Which factor is likely to impact the possible number of compounds? presence of unlimited number of elements in the periodic table the inability of atoms to align perfectly with other atoms the ability of all elements to react with every other element all elements being equally reactive
