Interpretation Introduction

Interpretation:

The changes that must be made to A to obtain the unit volumes in B and C is to be determined.

Concept introduction:

Dilution is the process of converting a concentrated solution into a dilute solution by adding the solvent. In the resultant solution, amount of solute remain fixed but the volume of the solution increases. The moles of solute before and after dilution remain fixed.

The expression to calculate the volume of the concentrated solution when number of spheres and volume of dilute solution and the number of spheres in diluted solution are given is as follows:

$V_{\text{conc}}=\frac{N_{\text{dil}}{V}_{\text{dil}}}{N_{\text{conc}}}$

Here,

$N_{\text{dil}}$ is the number of sphere present in diluted solution.

$V_{\text{dil}}$ is the volume of diluted solution.

$N_{\text{conc}}$ the number of sphere present in the concentrated solution.

$V_{\text{conc}}$ is the volume of concentrated solution.
