Concept explainers
(a)
Interpretation:
A plot between partial molar volume of ethanol and its molality has to be done. The composition at which the partial molar volume is minimum has also to be determined.
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.
(b)
Interpretation:
By using differentiation tool the minimum in part (a) has to be identified.
