Oil droplet mass of .000000885 kg and a density of 923 kg per cubed m that spreads out to form a circle with a radius of 43.2 cm what is the approximate diameter of an oil molecule in units m?
Cathyyf
43.2 cm is .432 m
(pi)r2 = area of circle = 0.586 m2
.000000885kg/923kg/m3 = 9.59e-10 m3 = volume of oil cylinder
volume/area = thickness
1.64e-9 m

How can one easy calculate the kinetic diameter or an equivalent measure of a given molecule?
Firstly, calculate the molecular volume by dividing the product of molecular density and the molecular weight by the Avogadro number. Then take a third root of the volume, the found value is the atomic radius. Then multiply it by 2 to find the diameter.
Density of 0.95 reaction in water?
There are too many different compounds with an approximate relative density of 0.95 for this question to be answered.
What is the density of a sphere with a diameter 5cm and a mass of 10g?
Diameter = 5 cm so volume = 4/3*Ï€*(d/2)3 = 65.45 cm3 Then density = 10/64.45 = 0.1528 grams per cm3
What is the approximate density of a piece of aluminum if its mass is 13.5 g and volume 100cm?
0.135 g/cm3
A meteriod with a diameter of 1cm strikes the Moon What will the crater diameter be?
That would depend on several factors; the velocity of the meteoroid, the mass, density and composition of the meteoroid, and the nature of the surface where it strikes.

Where is the density of electrons greatest in the water molecule?
The density of electrons in a water molecule is highest around/near the oxygen atom.

What is the approximate density of stephenson county?
this is not a county in west Virginia
What caused density?
If there are more molecules in a given volume of air, the density is greater. If there are fewer molecule, the density decreases. Density=Mass/Volume

Weight calculation from height and diameter?
Height and diameter will give you the volume, if you know the density you can then calculate weight from that.

What is the diameter of a spherical protein if the protein is spherical and has a density of 1gcm3?
To answer this question, the mass of the spherical protein is needed. the fact that the protein is a sphere and that it has a density of 1gcm3 is not enough information to determine the diameter.
How can you demonstrate ther is space between molecules of water?
Calculate volume of molecule, calculate mass of molecule, compare to bulk density. Lower bulk density indicates empty space.
How dense is the sun?
The sun has an approximate density of 1.4 g cm-3. It is only an approximation because the sun's density varies.
How do you estimate the density of francium hydroxide?
The density of francium hydroxide was not estimated; an approximate estimation can be made by comparison with the alkali metals hydroxides.
