In this case any link with Avogadro number exist. Avogadro number is a constant.
During the boiling water is evaporated.

so the solution will not be contaminated or changed during the reaction
The liquid is evaporated.
If the solution in the conical flask gets washed with distilled water during the experiment, it can potentially dilute the solution, change its concentration, or introduce impurities. This can impact the accuracy and reliability of the experimental results. It is important to follow the experimental procedure carefully and avoid introducing any unintended changes to the solution.

The independent variable changes during an experiment.
Record your observations during an experiment. This will be part of the data you collect.
During distillation liquids are evaporated.
The independent variable changes during an experiment.
Evaporated liquid from the solution (transformed in gas) or gases released by thermal decomposition and condensed in the cooler part of the test tube.
It means what you saw during the experiment.
