Respuesta :
Dilution is a process of adding more solvent to a solution to decrease the concentration of the solution. In the process, the number of moles of solute does not change and only that of the solute change particularly increased. The answer to this problem is the first statement.
The number of moles of solute do not change is true regarding dilutions.
What is dilution?
Dilution is a process where we add solution or solvent as to increase the volume.
In the process of dilution we add solvent to the solution to increase the volume and decreases the concentration of solute. So, the moles of solute do not change in the solution, but the moles of solute per unit volume changes as the volume increases due to dilution and solute may travel in different position.
Hence, option (a) is correct.
