In a binary liquid system, the excess molar volumes of species 1 and 2 at a constant temperature of 25ºC is represented by the following equation:

V^E=x₁x₂[-1.026-0.220(x₁-x₂)] in cm³/mol

Given that the pure species molar volume V₁ = 40.44 cm³/mol and V₂ = 116.3 cm³/mol, you desire to form from 1000 cm³ of each pure species 1 and 2 a mixture at 25ºC.

1.  Calculate the mole fraction of species 1 in the mixture. (3)
