1. Find the volume of one drop:

* Divide the total volume (0.1 fluid ounce) by the number of drops (1000):

0.1 fluid ounce / 1000 drops = 0.0001 fluid ounce/drop

2. Calculate the volume of 10 drops:

* Multiply the volume of one drop by 10:

0.0001 fluid ounce/drop * 10 drops = 0.001 fluid ounce

Therefore, 10 drops of this liquid would have a volume of 0.001 fluid ounce.
