Chapter 4, Problem 4.4PR

(a)

Interpretation Introduction

Interpretation:

An expression for the partial molar volume of water and a plot between partial molar volume of water and molality of ethanol has to be done.

Concept Introduction:

Partial molar volume:

The partial molar volume is defined as the contribution that a component of a mixture makes to the overall volume of the solution.

Molality:

The molality (m) of a solution is the moles of solute divided by the kilograms of solvent.

$Molality(m)=\frac{Molesofsolute}{Ki\log ramsofsolvents}$
