(A) The volume change of mixing of the system ethanol (1)/methyl butyl ether (2) at 25C is given by V(cm3/mol)=x1x2{1.026+0.22(x1x2)} The pure species volume V1=110cm3/mol and V2=90cm3/mol (a) 750cm3 of pure species of 1 is mixed with 1500cm3 of pure species 2 at 25C. (i) What would be the volume if an ideal solution is formed? (ii) Estimate the volume of the mixture is formed. (b) Derive the expression of V1 and V1E. (8+7)
