Answer : Volume range in milliliters for a solution is 0.25 ml to 0.5 ml.
Solution : Given, 1 ml = 20 drops
There are 20 drops present in = 1 ml of water
In 1 drop = [tex]\frac{1 ml \text{ of water}}{20\text{ drops}}[/tex]
And in 5 drops = [tex]\frac{1 ml \text{ of water}}{20\text{ drops}}\times 5 \text{ drops}[/tex]
= 0.25 ml
For range calculation, 0.25 ml is multiplied by the 2, we get
= 0.25 × 2
= 0.5 ml
Hence, the volume range is 0.25 ml to 0.5 ml.
