Number of Molecules vs Mass of Compound

Formula

## How to Count Molecules ### Formula **N = (mass / molar mass) × 6.022 × 10^23**

Esempio Risolto

How many molecules in 18 g of water?

  1. 01Moles = 18 / 18.015 = 0.999 mol
  2. 02Molecules = 0.999 × 6.022 × 10^23 ~ 6.02 × 10^23

Domande Frequenti

What is the difference between atoms and molecules?

Atoms are individual elements; molecules are two or more atoms bonded together. H2O is a molecule with 3 atoms.

How do I find total atoms from molecule count?

Multiply the number of molecules by the number of atoms per molecule.

Does this work for ionic compounds?

Ionic compounds form formula units, not molecules. The math is the same but the result is formula units.
