Frequent question: How do you convert between atoms and moles?

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:

  1. To go from moles to molecules, multiply the number of moles by 6.02 x 1023.
  2. To go from molecules to moles, divide the numbers of molecules by 6.02 x 1023.

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 = 6.02214076×1023 particles (atoms, molecules, ions etc.), 1 joule per mole is equal to 1 joule divided by 6.02214076×1023 particles, 1.66054×1024 joule per particle.

How do you calculate moles step by step?
