Ethanol, C2H5OH (molar mass = 46 g/mol) is mixed with methanol, CH3OH (molar mass = 32 g/mol) to make an ideal solution at a given temperature. If 5.00 g of ethanol and methanol are mixed, what is the resulting vapor pressure of the solution? (the vapor pressure at the same temperature for pure ethanol is 44.5 mm Hg and pure methanol is 88.7 mm Hg)
