Number of Atoms vs Mass of Element
Formel
## How to Count Atoms ### Formula **N = (mass / atomic mass) × 6.022 × 10^23** Convert grams to moles, then moles to atoms using Avogadro's number.
Lösungsbeispiel
How many atoms in 12 g of carbon-12?
- 01Moles = 12 / 12.011 = 0.999 mol
- 02Atoms = 0.999 × 6.022 × 10^23
- 03Atoms ~ 6.02 × 10^23
Häufig Gestellte Fragen
How many atoms are in one mole?
6.022 × 10^23 atoms, which is Avogadro's number.
Does this work for molecules too?
For molecules, this gives the number of molecules. To get total atoms, multiply by atoms per molecule.
Why is Avogadro's number so large?
Because atoms are incredibly small. It takes about 6 × 10^23 of them to make a countable, weighable amount.
