Answer : The volume range in milliliters for the solution is 0.25 - 0.5 mL
Explanation :
We have been given that there are approximately 20 drops per milliliter of water
This information can be used as a conversion factor as [tex] \frac{1mL}{20 drops} [/tex]
We are using 5-10 drops of the solution.
Let us calculate milliliters in 5 drops.
[tex] 5 drops \times\frac{1 mL}{20 drops} = 0.25 mL [/tex]
Similarly, 10 drops would contain
[tex] 10 drops \times\frac{1 mL}{20 drops} = 0.5 mL [/tex] solution.
Therefore the volume range in milliliters for the solution is 0.25 - 0.5 mL
