Final answer:
The normal commercial eye dropper typically dispenses about 20 to 40 microlitres (μL) of solution. An eyedropper holds about 1 milliliter (mL), which is equivalent to 1000 microlitres. So, if we divide 1000 μL by the number of droplets, we can estimate the volume of each droplet.
Step-by-step explanation:
The normal commercial eye dropper typically dispenses about 20 to 40 microlitres (μL) of solution.
An eyedropper holds about 1 milliliter (mL), which is equivalent to 1000 microlitres. So, if we divide 1000 μL by the number of droplets, we can estimate the volume of each droplet.
For example, if we assume that the eyedropper dispenses 40 μL per droplet, then 1000 μL / 40 μL = 25 droplets. This means that each droplet would be approximately 40 μL / 25 = 1.6 μL.
