What is the volume of a drop liquid?

The volume of a liquid drop depends on the liquid itself, the size of the drop, and external factors like temperature and air pressure. It's not fixed and can vary. But here are some approximate ranges for the volume of a single drop of various liquids:

1. Water: 0.05 to 0.1 milliliters (mL)

2. Milk: 0.05 to 0.15 mL

3. Olive Oil: 0.04 to 0.08 mL

4. Gasoline: 0.04 to 0.1 mL

5. Glycerin: 0.03 to 0.06 mL

6. Mercury: 0.02 to 0.04 mL

7. Ethanol: 0.05 to 0.08 mL

Keep in mind that these values can fluctuate based on factors like the specific liquid's density, surface tension, and the specific dropper or method used to form the drop.
