The mole is defined as the number of atoms in exactly 12 gg of carbon-12. The mole equals 6.022×10236.022×1023 items of whatever you are counting. This number is also called Avogadro's number, after Amadeo Avogadro (1776–1856). Molar mass is the mass of 1 molmol of atoms of an element; for compounds, molar mass is the mass of 1 molmol of molecules or formula units. Molar mass can be used to convert mass to moles for any element or compound. How many water molecules are in a block of ice containing 2.00 molmol of water (H2OH2O)?

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
