# Avogadro's Number, The Mole & Molar Mass

## ✰ The Mole and Avogadro’s Number 📺

• This video conceptualizes the definition of a mole of a substance as being equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number.

## ✰ The Relationship of Moles to Atoms and Molecules 📺

• This video explains the concept of moles and how it relates to mass in grams by the molar mass of a compound. It also explains how moles relate to atoms and molecules through Avogadro's number.

## ✰ Avogadro’s Number, The Mole, Grams, Atoms, and Molar Mass Calculations 📺

• This video focuses on Avogadro's number and how it is used to convert moles to atoms. This video also explains how to calculate the molar mass of a compound, and how to convert from grams to moles.

## ✰ The Mole and Molar Mass, Study Guide 📖
