The Mole: Avogadro's Number and Stoichiometry
Guided Notes
3 key concepts
- 1
A mole is a very large number, specifically 6.022 x 10²³, and is called Avogadro's number.
- 2
The molar mass of a substance is the mass of one mole of that substance, expressed in grams.
- 3
In stoichiometric calculations, you can convert from mass to moles of one substance, then to moles and mass of another substance using mole ratios from the balanced equation.

“If you start with 10 grams of methane (CH₄) in a combustion reaction, how many grams of carbon dioxide (CO₂) will be produced? Show all steps, including calculating molar masses, converting to moles, using the mole ratio, and converting back to grams. The balanced equation is CH₄ + 2O₂ → CO₂ + 2H₂O.”
