Question

Depending upon the tip of a dropper pipet there are approximately 20 drops per milliliter of water. the experimental procedure part a and b indicates the addition of 5 -10 dropps of each solutions to the test tubes calculate the volume range in milliliters for the solution

Answer 1

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 $\frac{1mL}{20 drops}$

We are using 5-10 drops of the solution.

Let us calculate milliliters in 5 drops.

$5 drops \times\frac{1 mL}{20 drops} = 0.25 mL$

Similarly, 10 drops would contain

$10 drops \times\frac{1 mL}{20 drops} = 0.5 mL$ solution.

Therefore the volume range in milliliters for the solution is 0.25 - 0.5 mL
