4. A student performed the experiment but varied the volumes used when weighing out the liquids. For the 0% salt solution, the student used 13.2 mL, for the 5% solution the student used 12.9 mL and so
on. Assuming everything else was performed precisely and accurately, will the differing volumes
affect the outcome of the experiment? Explain your answer.
