Pragice work:

$($need to kearn deeply$)$

As a chief engineer, you are told by one of your staff that the partial molar volume of species $A$ in a binary mixture of A and $B$ at constant $T,P$ can be modeled as:

$\frac{?}{\text{b}\text{a}\text{r}}(V{)}_A=21-2(1-x_A{)}^{2}c\frac{m^3}{m}ol$

a$)$ Based on this model, formulate $\frac{?}{\text{b}\text{a}\text{r}}(V)B$ as a function of $xB,$ if $VB=18cm\frac{3}{m}ol.$

b$)$ Determine $\frac{?}{\text{b}\text{a}\text{r}}(V{)}_A^{}$ and $\frac{?}{\text{b}\text{a}\text{r}}(V{)}_B^{}$

please solve part AdB with knowledse of thermodynamics shiw work to explain
