Answer:
The answer is 0.1 fluid ounce.
Explanation:
In order to determine the volume of 1000 drops, we have to know the volume of one drop. We can get this value using the proportion method.
In this method, we make equalities between fractions. The fractions must be in the same order. The numerator will be the amount of drops and the denominator will be its volume.
x=volume of one drop.

Then, we need the volume of 1000 drops, so we just multiply the volume of one drop by 1000.

Finally, the volume of 1000 drops is 0.1 fluid ounce.
