A mole is a counting number that describes the number of Carbon atoms in 12 grams of $^{12}C$ and known as Avogadro's number or $6.022*10^{23}$. The mole concept is important in describing the rearrangement of atoms during a reaction and relating number and quantities of reactants and products with each other.

Work Step by Step

A mole is a counting number that is about $6.022*10^{23}$. The mole is used in stoichiometry in determining the amounts of reactants consumed and products formed in a chemical reaction to count a large number of atoms quickly and efficiently.
