Enter the total number of atoms and the average atomic mass into the calculator to determine the mass of the atoms.

## Mass of Atoms Formula

The following formula is used to calculate the mass of atoms.

 M = a * am
• Where M is the mass in grams
• a is the total number of atoms
• am is the average atomic mass (Amu’s)

To calculate the mass of atoms, multiply the number of atoms by the atomic mass.

## Mass of Atoms Definition
