Mole- used to convert from atomic mass units to grams Scientists use the mole as a unit of measurement Abbreviation= mol Amedeo Avogadro discovered the mole Avogadro’s number= 6.02 x 10 23

Stoichiometry- The use of the amount of particles, the mass or the volume of a reactant or product to calculate the amount of particles, the mass or the volume of another reactant or product.

Write balanced chemical equation Convert quantities of known substances into moles Use coefficients in balanced equation to calculate the number of moles of the sought quantity Convert moles of sought quantity into desired units
