Enter the number of atoms per unit cell, the atomic weight, and the volume of a unit cell into the calculator to determine the theoretical density.

## Theoretical Density Formula

The formula for calculating the theoretical density is as follows:

p = (n*A)/(V*N)

- Where p is the density (g/cm^3)
- n is the number of atoms per unit cell
- A is the atomic weight (g/mol)
- V is the volume per unit cell (cm^3/cell)
- N is Avogadro’s number (6.023*10^23)

## Theoretical Density Definition

A theoretical density is defined as the maximum density of a material or element that could be achieved assuming there are no voids or contaminants in the overall material.

## What is the theoretical maximum density?

The theoretical maximum density of an element or material can be calculated using the formula p = (n*A)/(V*N). This represents the true or maximum density the material can reach in a given sample.

## How to calculate a theoretical density?

- First, determine the number of atoms per cell of material or element.
- Next, determine the atomic weight. Calculate the average weight of all of the elements in the material.
- Next, determine the volume per unit cell. Typically this is 1 cm^3 per cell.
- Finally, calculate the theoretical density. Using the formula along with Avogadro’s number, you can calculate the theoretical density.
