Stoichiometry

• The word "stoichiometry" is derived from 2 Greek words, ( Stoichio - Element ), Metry - Measure

• Stoichiometry is ratio of products and reactants in balanced symbol equation

Mole

• The mole describes the amount of substance, mole is a unit

• 1 Mole = 6.022 x 10^23

• Example -:

  1 Mole Of Water Molecule = 6.022 x 10^23

  1 Mole Of Electron = 6.022 x 10^23

  1 Mole Of Atom = 6.022 x 10^23

Why 6.022 X 10^23 ?

• The term 6.022 x 10^23 was introduced by scientist as a universal understanding

• As 12 Grams of carbon = 6.022 x 10^23 Carbon atoms

Molar Mass

• The mass of one mole of a substance is called its molar mass

• Number Of Moles -: Mass/Molar Mass

Avogadro Constant

• The Avogadro's constant represents the number of particles in a substance

• Avogadro's constant = 6.022 x 10^23
