Moles to Atoms Converter

Q: How do I convert atoms to moles?

To convert atoms to moles: Write down the number of atoms. Divide the number of atoms by Avogadro's number (6.02214076 × 10 23 mol -1 ). That's it. This gives you the number of moles.

Q: How many moles are in 6.02 × 10^23 atoms of magnesium?

About 1.00 mol. To convert atoms to moles, divide the number of atoms by Avogadro's number: Moles = 6.02 × 10 23 /6.02214076 × 10 23 ≈ 1 mol There is 1.00 mole of magnesium in 6.02 × 10 23 atoms.

Q: How do I calculate moles?

If you want to know how many moles of a material you have, divide the mass of the material by its molar mass. The molar mass of a substance is the mass in grams of one mole of that substance.

Q: Does 1 atom equal 1 mole?

One mole of a substance is equal to 6.02214076 × 10 23 units of that substance (such as atoms, molecules, or ions). The number 6.02214076 × 10 23 is known as Avogadro's number or Avogadro's constant.

What is a mole?

The mole ( $\text{mol}$ ) is one of the base units of the International System of Units (SI), adopted in 1971, which is primarily used in physics and chemistry. Back then, it was defined as the number of elementary entities, equivalent to the number of atoms in 12 grams of carbon-12. Since May 2019, the mole is the amount of matter in a system containing exactly $\rm{6.02214076 × 10^{23}}$ elementary entities (atoms, ions, molecules, etc).

This number, called "Avogadro's number", corresponds to the fixed numerical value of Avogadro's constant, $N_{\text{A}}$ , when expressed in $\mathrm{mol^{−1}}$ .

You can learn more with our following articles: "What is a mole?" and "What is Avogadro's number?".

How to convert moles to atoms

To convert moles to atoms, multiply the number of moles by Avogadro's number:

\text{Atoms} = \text{Moles} \times 6.02214076 \times 10^{23}

This calculation tells you exactly how many atoms are present in a given amount of substance.

🔬 Quick explanation of Avogadro's number

Avogadro's number (6.02214076 × 10²³) is a fundamental constant in chemistry that tells us how many particles are in one mole of a substance. This number is huge, but it allows chemists to bridge the gap between the microscopic world of atoms and the macroscopic world we can measure in grams and liters. It's what makes stoichiometry possible.

How to convert atoms to moles

To convert atoms to moles, divide the number of atoms by Avogadro's number:

\text{Moles} = \frac{\text{Number of Atoms}}{6.02214076 \times 10^{23}}

where $(6.02214076 \times 10^{23} \ \mathrm{mol^{-1}})$ is, as you know now, Avogadro's constant, i.e., the number of atoms in exactly one mole of a substance.

That's it! This is how to calculate atoms from moles. Easy, isn't it? This conversion is commonly used in stoichiometry when analyzing chemical reactions.

How to use our atoms to moles converter

Our moles to atoms converter is very easy to use:

To find the number of atoms, enter a value in the Number of moles field.
To find the number of moles, enter a value in the Number of atoms field instead.
In both cases, the result will automatically appear in the other field, and we show the complete step-by-step calculation at the bottom of the calculator.

Example: How to calculate atoms from moles by hand

Suppose you have $\mathbf{0.50}$ moles of carbon atoms. Let's convert it to the number of atoms:

\begin{align*} \text{Atoms} &= \rm{0.50} \times 6.02214076 \times 10^{23}\\ & \approx 3.011 \times 10^{23} \end{align*}

Therefore, you have approximately $\mathrm{3.011 \times 10^{23}}$ carbon atoms
