Chapter 10, Problem 10.7P

Interpretation Introduction

(a)

Interpretation:

The partial molar mass of a species in solution is equal to its molar mass.

Concept introduction:

The mathematical expression of partial molar mass is given by:

${\overline{m}}_i={\left[\frac{\partial (m)}{\partial n_i}\right]}_{T,P,n,j}$

where, m_iis the mass of the ith solution.

M_i is the molar mass of the solution.

Now,,

$m=n_i{M}_i+n_j{M}_j$

Interpretation Introduction

(b)

Interpretation:

A partial specific property of a species in solution is obtained by division of the partial molar property by the molar mass of the species.

Concept introduction:

The partial specific property of any substance is actually explained as the partial molar property divided by the partial molar mass.

To show the result of division of partial molar property by molar mass of a species in any solution, the partial molar equation is used.
