## 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.
हल किया गया उदाहरण
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
अक्सर पूछे जाने वाले प्रश्न
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.
