C2H5OH: Molality: 5.0 g C2H5OH 100 g solution 1 mol C2H5OH 46.07 g C2H5OH 100 g solution 95 g solvent 1000 g solvent 1 kg solvent = 1.1 molal Mole fraction: 5.0 g C2H5OH 1 1 mol C2H5OH 46.07 g C2H5OH = 0.11 mol C2H5OH and for water: 95 g H2O 1 1 mol H2O 18.02 g H2O = 5.27 mol H2O X C 2 H 5 OH = 0.11 mol C2H5OH 5.27 mol H2O . Pure ethanoic acid (25.0cm3, CH3COOH), pure ethanol (35.0 cm3, C2H5OH) and pure water (20.0cm3, H2O) were mixed in a sealed flask at room temperature. Thus, like the dissolution of any water-soluble ionic compound HCl converts completely to ions in water. (C2H5OH), benzoic acid forms ethyl benzoate, an ester (C6H5CO-O-C2H5). Some of this early work (1-3) is in good Water was replaced with ethyl alcohol and complete dissolution of scheelite was achieved with HC1-C2H5OH.-H20 (25% H20, v/v) and HC1-CzH5OH solutions. Water was replaced with ethyl alcohol and complete dissolution of scheelite was achieved with HC1-C2H5OH.-H20 (25% H20, v/v) and HC1-CzH5OH solutions.
