Enter the total number of atoms of a substance and the average atomic mass of the substance into the calculator. The calculator will convert the total atoms to grams.

Atoms to Grams Formula

The following equation is used to calculate the total number of grams from atoms.

G = A * AAM

  • Where G is grams
  • A is the total number of atoms
  • AAM is the average atomic mass of the atoms

Atoms to Grams Definition

Converting atoms to grams involves multiplying the total number of atoms by the average atomic mass of the atoms.

How to convert atoms to grams?

Example Problem:

First, determine the total number of atoms in the substance. Calculate the total number of atoms you are measuring.

For this example, simple numbers will be used. The number of atoms in the substance is found to be 50.

Next, calculate the average atomic mass (AAM). For more information on how to do this, you can visit the average atomic mass calculator linked above.

In this case, the AAM is found to be 3g/atom.

Finally, calculate the amount of grams in the substance using the formula above:

G = A * AAM

G = 50 * 3

G = 150 grams
