## How much atoms is in a mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = **6.022 × 1023 atoms** • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## How do you convert molecules to moles?

**Converting between molecules and moles is done by either multiplying by or dividing by Avogadro’s number:**

- To go from moles to molecules, multiply the number of moles by 6.02 x 10
^{23}. - To go from molecules to moles, divide the numbers of molecules by 6.02 x 10
^{23}.

## How many atoms are in 2 moles?

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 ^{23}) Na atoms, or **1.2044 × 10 ^{24} Na atoms**.

## How do you convert moles to joules?

Since 1 mole = 6.02214076×10^{23} particles (atoms, molecules, ions etc.), **1 joule per mole is equal to 1 joule divided by 6.02214076×10 ^{23} particles**, 1.66054×10

^{−}

^{24}joule per particle.
