An ethanol-water solution containing 55 mole% of ethanol and 45 mole% of water is to be prepared at 25C. Estimate the amounts (c * m ^ 3) of ethanol and water to be mixed to form one litre of solution, and the volume change in mixing. [11 marks) Solution property data: Ethanol/ water sohitis (23) Partial molar volumes for 55 mol% ethanol - 57.5c * m ^ 2 * inv*l_{c} and 45 mol% water = 17c * m ^ 2 / m * ol

Molar volumes of pure ethanol sl = 58.3682cm ci * n ^ 2 / mbl, and ma * der = 18.0742c * m ^ 3 / m * ol
