3.18 A mixture of ethanol(1) and water(2) has x₁ = 0.7 and a density p = 0.8306 g/cm³. At these conditions, the partial molar volume of water is V₂ = 15.68 cm³/mole. (a) What is the value of V₁, the partial molar volume for ethanol? (b) Estimate the mixture density p when x1₁ is changed from 0.70 to 0.71 at fixed T and P. (c) Do you expect V₁ to increase or decrease when x₁ is increased from 0.70 at fixed T and P? Justify your expectation and clearly cite all assumptions made.
