A mole is a unit used to count particles like atoms or molecules.

One mole equals 6.022 x 10²³ particles (Avogadro’s number).

Molar mass is the mass of one mole of a substance.

The mole helps chemists measure substances in reactions.

One mole of carbon-12 weighs exactly 12 grams.

Mole ratios are used to balance chemical equations.

Mole calculations connect mass, number of particles, and volume.

Gas volumes at standard conditions are related to moles.

Moles help in determining concentration in solutions.

The mole concept bridges atomic scale to everyday amounts.
