The molar volume (cm3• mol-1) of a binary liquid mixture at Tand Pis given by: V=100x1+80x2+(20x1+10x2)x1x2 (a)Find expressions for the partial molar volumes of species 1 and 2 at Tand P. (b)Show that when these expressions are combined in accord withM=E;x;M;the given equation for V is recovered. (c)Explain the Gibbs/Duhem equation and its applications. (d)Show that these expressions satisfy the Gibbs/Duhem equation. (e)Show that (dV1/dx1}m=1=(dV2/dx1)x1-0=0
