Answer : The number of drops it takes from a dropper to dispense 1.0 ml of ethanol is, 20 drops
Solution : Given,
Density of ethanol = 0.80 g/ml
Mass of ethanol = 0.60 g
First we have to calculate the volume of ethanol.
Formula used : 
The volume of ethanol is, 0.75 ml
Now we have to calculate the number of drops it takes from a dropper to dispense 1 ml of ethanol.
As, the number of drops in 0.75 ml of ethanol = 15
So, the number of drops in 1.0 ml of ethanol = 
Therefore, the number of drops it takes from a dropper to dispense 1.0 ml of ethanol is, 20 drops

The molecular geometry of a molecule with a core atom that has five areas of electron density and precisely one lone pair of electrons is called a disphenoidal or seesaw molecular geometry.
What is meant by disphenoidal or seesaw molecular geometry?
- Four bonds are made to an atom in the center of a disphenoidal or seesaw-shaped molecular structure, which has overall C2v structural symmetry. The fact that it resembles a playground seesaw is how it got the moniker "seesaw." Tetrahedral or, less frequently, square planar geometry is produced when four bonds to a center atom are present.
- The core atom of a molecule with a steric number of 5 and bonds to 4 additional elements and 1 lone pair is said to be in the seesaw geometry.
