The volume change of mixing (cm3 mol-1 ) for the system ethanol (1)/ methyl butyl ether (2) at 25 ℃ is given by the following equation: ΔV = x1x2[−1.026 + 0.220(x1 − x2)] Given that V1 = 50.63 cm3 and V2 = 110.46 cm3mo−1 , what volume of mixture is formed when 700 cm3 of pure species 1 is mixed with 1,400 cm3 of species 2 at 25 ℃? What would be the volume if an ideal solution were formed?
