Tut, tut. Doing your homework for you.

Well work it through...

First of all, how much does 1.0ml of ethanol weigh? A quick search tells you it's density is 0.789g/ml. Therefore, 1ml of ethanol weighs 0.789g.

Next. If 15 drops of ethanol weigh 0.6g, 1 drop weighs 0.04g (0.6/15).

Finally, we want 0.789g, each drop weighs 0.04g so how many 0.04s are there in 0.789?


19.725 drops of ethanol make up 1.0ml; but since this is unrealistic, 20 drops (rounding up) weighs 0.8g so gives you 1.01ml.

It's commen sense actually,it's due to diff in air pressure by pressing it creates low pressure and outside is a gap higher pressure thus fluids movie from outside(high pressure to low pressure)to the inside of the dropper.

A dropper is used to drop a little amount on your apparatus. A dropper is used to dispense small amounts of a liquid. It is especially useful when the amount to be added is very small and needs to be measured accurately.

There would be 4 drops per dose.

How would you measure 40 drops of medicine using a medicine dropper?

Typically there are about 20 drops in 1 mL of liquid. Get a graduated cylinder marked with Milliliters. Start counting drops and fill until you get to 1mL To the previous wrong answerer, 1 drop is NOT 1 cc, think about it.

You call a very small drop of liquid a 'droplet'. A droplet is a smaller measurement of a drop of liquid and is usually used when talking about liquid particles that are less then 50 um in diameter.

How many drops is in 1mL of alcohol?

The volume of a drop of a given liquid depends on the shape and materials of construction of the drop dispenser. Ethanol interacts differently with glass than plastic, and differently with different kinds of plastic. The size of a droplet is also dependent on the surface area of the point at which the drop forms. Ethanol does not "bead" on plain glass surfaces. Instead it tends to spread out, because it interacts with the surface. On the other hand, ethanol, just like water, will bead on certain inert plastics, due to a lack of interaction with those materials (ie. doesn't "cling" to them). So a PTFE dropper, for example, will form smaller drops than a glass dropper, and a very narrow needle-like dropper tip will form smaller drops than a thick, blunt dropper tip. Based on the selection of one's dropper, the volume of a droplet of ethanol could vary by upwards of 150%.
