Question

A liquid dietary supplement is packaged in 10-ml dropper containers to deliver 2000 international units of vitamin d3 in each drop (0.027 ml). calculate the number of drops delivered per milliliter.

Answer 1

Answer : 37 drops are delivered per milliliter of the solution.

Explanation :

The problem gives us lot of extra information.

We want to find the number of drops delivered in 1 milliliter here.

We have been given that, one drop of the solution delivers 0.027 mL of solution.

Let us use this as a conversion factor, $\frac{1 drop}{0.027 mL}$

Let us find number of drops in 1 mL using this conversion factor.

$1 mL \times \frac{1 drop}{0.027mL} = 37.0 drops$

Therefore we can say that 37 drops are delivered per milliliter of the solution.
