Mass, Moles, and Avogadro's Number (Video Notes)

Vocabulary flashcards covering the key concepts from the video notes on relating mass, moles, and particles using Avogadro's number.

Avogadro's number

6.02 × 10^23; the number of particles in one mole of any substance.

Mole

The amount of substance that contains 6.02 × 10^23 particles; a bridge between mass and the number of particles.

Molar mass

Mass of one mole of a substance, expressed in grams per mole; used to convert grams to moles.

Gram

Unit of mass in the metric system; used to measure lab quantities and relate to moles via molar mass.

18 g of water = 1 mole

Example from the notes: 18 grams of water is one mole of water and corresponds to 6.02 × 10^23 water molecules.
