## Solved 1. Calculate the number of atoms contained in ...

1. Calculate the number of atoms contained in a cylinder 1 μm in diameter by 1 μm deep of gold. Density= 19.8 gram/cm 3, Atomic mass= 196.97 gram/mole . 2. A 10 μm diameter of SiO 2 optical fiber has density 2.20 Mg/ m 3.Calculate the number of O and Si atoms present per millimeter length of the optical fiber.

## How can you calculate how many atoms ... Sustainable

28/07/2016· The unit cell is a perfect cube, so its volume is 0.408 3 = 0.0679 cubic nm. The volume of a cube = length x width x height, all of which are 0.408 nm in this example. Even though the unit cells of gold nanocrystals are cubic, gold nanoparticles themselves are pretty much spherical in shape.

## Diameter of an Atom The Physics Factbook

The diameter of an atom ranges from 1 × 10 10 m to 5 × 10 10 m. There is no one definite diameter of an atom because since the number of electrons in the outer principal energy level increases as you go from left to right in each period, the corresponding increase in the nuclear charge due to the additional protons pulls the electrons more tightly around the nucleus.

## Calculating diameter of gold atoms in a cube : chemhelp

Calculating diameter of gold atoms in a cube. A cube of gold that is 1.00 cm on a side has a mass of 19.3 g. A single gold atom has a mass of 197.0 amu. A.) How many gold atoms are in the cube B.) from the info given estimate the diameter in Angstroms of a single gold atom C.) What assumptions did you make in arriving at your answer for part
