Unit 5 Stoichiometry Vocabulary

This is the amount of a substance that contains as many particles as there are atoms in exactly 12 g of carbon-12.

• Mole

• molar mass

• avogadro's number

• mole ratio

Explains the relationship between mass and numbers of atoms. The number equals 6.0221367 x 1023 rounded to 6.022 x 1023.
