Gasohol contains ethanol (C2H4OH)(l), which when burned reacts with oxygen to produce CO2(g) and H2O(g). Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. Answer (1 of 3): Mole fraction of C2H5OH = 0.050 mole fraction of water = 1-0.050 = 0.95 mass of water = 0.95 x 18 = 17.1 g = 0.0171 Kg molality of C2H5OH = 0.05 / 0.0171 = 2.924 m C2H5OH(aq) + CH3COOH(aq)===>CH3COOC2H5(aq) + H2O(l) When 1.00 mol of ethanol was mixed with 2.00 mol of acid in a 1.00 L flask, 0.86 mol of ester was formed at room temperature.
