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

To find the diameter of an oil molecule, we can use the formula for the volume of a sphere (V = (4/3)πr^3) to approximate the volume of the oil droplet. With the given mass and density, we can calculate the diameter of the oil droplet from its volume. With the same density, we can then approximate the diameter of an individual oil molecule.

How big is Buckminsterfullerene?
Buckminsterfullerene is a molecule composed of 60 carbon atoms arranged in a spherical structure. The diameter of a buckminsterfullerene molecule is about 0.7 nanometers.
What is the charge density of a molecule?
The charge density of a molecule refers to the distribution of charge within the molecule. It is usually calculated as the total charge of the molecule divided by the volume it occupies. This information is important for understanding the molecular structure and reactivity of the molecule.
How can one easy calculate the kinetic diameter or an equivalent measure of a given molecule?
The kinetic diameter of a molecule is typically estimated based on its van der Waals radius, which can be found in reference tables. Another approach is to use the Lennard-Jones potential parameters for the molecule to calculate its interaction potential with a surface, and then derive an effective size from this interaction potential. These methods can provide an approximation of the molecule's size for practical purposes.
Is SCO a polar molecule?
Yes, SCO is a polar molecule. This is because it has a net dipole moment due to the difference in electronegativity between sulfur and carbon, causing an uneven distribution of electron density within the molecule.

What is the approximate minimum stream velocity needed to keep a particle in motion that has a diameter of 10 centimeters?
The minimum stream velocity needed to keep a particle in motion can be estimated using the settling velocity equation. For a 10 cm diameter particle, the approximate minimum stream velocity would need to be around 0.03 m/s to keep it in motion. This value may vary depending on factors such as particle density and fluid properties.
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.
Where is the density of electrons greatest in the water molecule?
The density of electrons is greatest around the oxygen atom in a water molecule because oxygen is more electronegative than hydrogen, causing it to attract the shared electrons more strongly. This results in a higher electron density around the oxygen atom.
How dense is the sun?
The average density of the Sun is about 1.41 grams per cubic centimeter. This makes it more than 12 times denser than Earth. The core of the Sun is much denser, with densities reaching 150 grams per cubic centimeter.
